Sigbog has been playing League of Legends since Season 1 and is currently a Grandmaster level jungler.
Everyone has to play a support champion at some point. Even if you don't want to main it, you should have a couple of champions up your sleeve ready to bust out in case you get auto-filled or need to play support for any reason. I firmly believe that as a player you will be much better if you're able to empathize with and understand other roles, even if you can't play them incredibly well. It helps you appreciate more things, like mid roaming, support warding, top teleports, etc. Furthermore, with positional ranking coming in League of Legends Season 9, knowing champions for different roles may be incredibly useful.
Below is a list of champions that serve various roles, but all of which can be executed on without too much difficulty. They're definitely the type of champions that offer a lot of value to the team without too much necessity to spend hours mastering.
3 Main Support Types
One could argue there are more than three types of support champions, but for the purpose of simplicity, I've gone with 3 major categories or play styles for bottom lane supports.
Aggressively forcing fights and making plays
Playing the role of protector and saving allies
- Damage Dealers
Acting as a partial carry in the support role (usually for a specific reason)
Top Engage Support Champions
Engage champions are all about making plays, taking advantage of mistakes, and forcing fights to gain advantages. They do poorly from behind, but steamroll games when ahead. They tend to be the right style for people who want action, want to be a hero, and tend to skew aggressive. Most engage oriented champions are looking to get kills in lane and be the deciding factor of the game's tempo and team fighting.
Blitzcrank is simply iconic in League of Legends. This champion features a long range pull, a melee knock-up, a move speed & attack speed boost, and an AoE silence. He is a ton of fun to play and something everyone who might ever play support should learn. He is great at engaging or forcing fights as well as making picks. He can be a huge lane bully and has a ton of kill pressure. He can even help peel carries with his knock-up or a clutch pull away from your backline. If you like to force fights and make clutch plays from the support role, Blitzcrank is your guy... robot... whatever.
- Good against: Immobile and squishy champions like Nami or Lux. Particularly if they rely on crowd control to survive.
- Bad against: Tanky champions, particularly if they want to engage or have crowd control. Pulling an Alistar into your team is basically offering them a free hard engage.
Alistar is another engage powerhouse but instead of pulling enemy champions to himself, he charges in. . .like a bull. He has a headbutt charge that knocks people back, an aoe knock-up + stun, a stun that charges up, an AoE heal, and his ultimate drastically reduces damage he takes. He's perfect for charging in. His typical combo is to headbutt in, but before knocking enemies away, use his AoE knock-up stun to charge in and stun everyone around. He then uses his charging stun which will let him stun someone again after it completes. Plus he can easily do this into multiple enemy champions because his ultimate reduces the damage he takes. Of course, when he charges in he has no good way of getting out.
- Good against: Squishy champions, particularly ones that can't stop his headbutt after he starts charging.
- Bad against: Other high crowd control tanky teams who don't mind getting stunned, long range poke, or disengage that stops his allies from being able to follow up.
My personal favorite and arguably one of the most bad-ass women in League of Legends, Leona dishes out crowd control like crazy. She has a ranged snare + engage, a melee stun, a long range AoE slow + stun, and a shield that detonates for extra damage. Somewhat similar to Alistar, Leona is about dashing in, locking someone down, and killing them. Unlike Alistar, she can use her long range aoe stun to lock down enemies with ease where Alistar needs to charge in. Her typical combo is to snare in, melee stun, drop her AoE stun, and by that time the enemy champion should be dead. Alternatively she can drop her AoE ranged stun to lock someone down, making it much easier to land her ranged snare and melee stun combo. She is a menace in lane starting at level 6 and for the rest of the game.
Good against: Squishy immobile champions with weak disengage.
Bad against: Long range poke, melee tanks, strong disengage, and of course... Morgana.
Top Disengage Support Champions
Disengage champions are all about preventing hard engage, keeping people alive, particularly those that can hyper carry games as they scale up. This can take the form of defensive crowd control, but also in healing and shielding. They tend to be great champions for people who want to foster a team mentality and work as a cohesive unit. They tend to be best in the hands of people who communicate and aim for consistency rather than explosive action. They don't necessarily counter all engage, it does depend on the champions themselves, but many do and you should pay attention to who and how.
Janna has a shield that increases attack damage, a targeted slow, a long range knock-up, and an aoe heal + knock back for an ultimate. She is amazing at disengage. She thrives in lane by harassing lane opponents and using her disengage and shield when they try to trade. As the game goes on, it's her job to keep the carries safe, shielded, and protected. Ideally the enemy team attempts to engage, gets disengage by Janna, and then your ally team re-engages after they've blown key cooldowns and are trying to escape. She's ideal when paired with hard carry champions.
Good against: Harass in lane, or dashing hard engagers.
Bad against: Ranged magic casters, particularly ones with crowd control.
Soraka is fairly simple, she is the quintessential healing champion in League of Legends. Though some may argue healing is a separate playstyle than disengage, in Soraka's case she can meaningfully peel off engagers. She has a heal, an aoe silence, a range harass + slow, and a global heal. It's her job to stay far in the back and keep everyone healed up while occasionally throwing out ranged slow harass. If someone gets too close and wants to make a hard engage, she can silence them to stop it. She should also pay attention to the entire map and heal allies elsewhere that may need it. Overall she can be very frustrating to fight against.
Good against: Lane harass, and generally anyone and anything that does instantly kill an ally.
Bad against: Assassins (particularly invisible ones), ranged crowd control if she gets locked down, burst damage, and hard engage if she goes too close.
Nami is similar to Janna and Soraka combined, though she is more difficult to execute on. She has a ranged harass + heal, a ranged AoE knock-up, a buff to an ally champion's basic attacks, and a giant long range wave that knocks up and slows for an ultimate. Her ultimate is probably single-handedly the best disengage tool in the game. Her harass + heal makes it difficult to trade against her and her ranged knock-up can let her make picks or prevent engages. However, it is very difficult for her to disengage before she has her ultimate because she has to land that skillshot AoE knock-up.
Good against: Melee tanks without hard engage, damage oriented bot lanes without heal / sustain
Bad against: Blitzcrank
Taric is a beautiful melee utility champ. He can link to ally champions to simultaneously cast spells from both the ally and himself including a stun, heal, shield, and invincible. He has a short range stun, a small AoE heal, a shield, and a small AoE invincibility spell for an ultimate. He is best at forcing hard engagers to have wasted their spells by turning invincible, stunning them off, and healing any damage. These skills can also be used as engage but they are fairly slow, small range, and difficult to force properly, so he is better off as disengage.
Good against: Hard engage
Bad against: Ranged harass, burst damage, and assassins.
Top Damage Dealing Support Champions
Damage champions are for greedy people that want to see kills in lane but engage champions just aren't quite enough. Damage champions can still get kills from behind, but they do tend to be riskier. They also tend to require lane partners that have their own survivability as their utility is much lower. They carry a bad rap for being 'players that got auto-filled into support' but there is a time and place for a damage lane. I generally advise to think carefully about what your team needs and not just go after a damage dealing support because other supports are boring to you.
Morgana is interesting, generally considered to have no hard counter, Morgana fills a lot of roles fairly well. However, her spells generally focus on crowd control and damage, and she is sometimes played in the mid lane. She has a long range snare with a long duration, an AoE magic damage pool that reduces resistances, a black shield that prevents crowd control and absorbs magic damage, and an AoE snare + stun over time for an ultimate. She can do reasonably well getting picks with her long range snare and if she gets into a team fight well her ultimate can lock everyone around her down into a stun. She can be quite a menace against one person as well as many. However, she can also use her black shield to prevent crowd control on an ally. This could make peeling off an assassin easier, or forcing an engage with an ally champion easier as well. Realistically, you have to outplay her to deal with her in lane. For example, her black shield can block all of Leona's stuns, meaning you have to bait the shield out, or use those stuns on the other person.
Good against: Any caster, any crowd control oriented champion, as well as squishy champions in lane that have no mobility to dodge her snare
Bad against: High mobility melee bruisers that don't need crowd control, and probably physical assassins.
More of a mid laner than a support, Lux features incredible long range damage, crowd control, and even some utility. She has a double long range snare, a long range AoE slow, a skillshot AoE shield for allies, and a super long distance blast for an ultimate. With her crowd control she can peel for allies or lock down enemies at a distance. With her shield she can protect multiple allies at once, though her shield is very weak. With her ultimate she can dish out a ton of damage.
Good against: Ranged casters, melee tanks without hard engage, anyone with low mobility
Bad against: Hard engage that has some range like a Blitzcrank or Alistar as well as high mobility champions that can dodge skillshots easily
It's a stretch to call Brand a support, he is purely damage oriented. He has a single target skillshot stun, a skillshot AoE damage spell, and a targeted single or AoE damage spell, and a bouncing targeted damage spell for an ultimate. He just starts everything on fire. When he starts someone on fire, his spells have extra perks. If he starts someone on fire 3 times, they will count down and burst into AoE damage. He is incredibly useful at spreading high amounts of AoE damage in team fights and is one of the few champions that could be played as support, on a team with 4 physical damage champions, and still dish out enough magic damage to be satisfied. His combo includes using his targeted spell to start someone on damage, then his ranged stun to lock them down, then his AoE skillshot to hit the 3rd spell and trigger the explosion. Throwing his ultimate out in team fights is also just incredibly because it will bounce back and forth on enemy champions. He is a lot of fun, but offers 0 utility to his lane partner.
Good against: Teams, short range casters, lane harass, or sustain lanes.
Bad against: Hard engage, longer range casters
I hope this list has helped you! These are just a handful of many possible support champions that act as good places to start. There are plenty more, some of which you could argue belong on this list. Let me know what you think if you think I should add someone!
