AP yi is a carry yes?

He is a squishy who runs around looking for ways to do tons of damage with very little cc often dependant upon his team to protect him yes? He tends to survive by healing like all other carries ja?

Carries tend to be a major source of damage on any team and tend to outmanuever many champs by healing evading juking and dealing tons of damage fast. The best champs for killing them such as assassins, heavy damage CC mages, fighters, bruisers, and anticarries are an important part of any team but it means nothing if everytime you teamfight everyone just throws everything they got at whomever they can.

Give team members responsibilities. AP yi is only strong because his job is obvious. Press R and Q people who might die. rinse repeat. He plays like a really poorly made assassin with a cute ability reset gimmick. He still functions like a carry but with a rather awkward way of healing. If you've ever seen fiora or vayne with bloodthirster youll notice that they too can tank your whole team and they too get melted the second they get CC'd. Most support champs can CC him and have time to do so as they have no business in the front lines of the battle anyways. Focus yi, kill yi, consider the enemy carry killed and celebrate.

If you have an assassin you are in especially good luck since most assassins can dump on yi and kill him as he tries to meditate or as soon as he comes out of alphastrike. Sometimes before.

In lane, do not treat him like a mage. He builds AP but he is not a mage. Poke him if you can and force him to blow his pathetic manapool. Out of all mana champs he possesses the 7th most bad manapool in the game and must save for his heal. I forget what it looks like but make sure if he seems to have his passive up that he doesnt get a chance to alphastrike on top of you. He cannot burst without items so hp pots or whatever sustain you have will be satisfactory to last against him if you need to reach level 6 or something. He must push lane to alphastrike 1 minion amongst many. Let him, he has no escapes. Freeze the lane and call for ganks or just attack him if you can keep up with him. Just remember that he's a carry with high move speed and an AS and damage steroid not that you should be in melee combat with his non AD building self ever.

Dont worry about chasing him if he seems determined to escape, he'll probably get away and is too squishy to do much without HP. BTW be sure to check his stats for unusual levels of MR and all that depending on who he has expecting to lane against. Especially if he's using MR per level or something.

AP yi doesnt snowball particularily hard, he just doesnt snowball like a mid mage or mid assassin. He is a carry champ regardless of how he builds and thus scales like a carry until he reaches any limitations he may have such as the inability to use much outside of alphastrike for damage.

Hard cc shuts down yi, Soft cc shuts down yi, MR shuts down yi

Anything from a Stun, Silence, Knockup, Suppress, Knockback all shut down yi when he heals.

Ignite, nomnomnomicon, Executioners Calling all stop his heal.

Any character that has grievous wounds attached to an ability shuts down his heal.

I dont see what the problem is.

even if you can't and you have no CC, this game isn't all about kills. Walk away if you must. He can't heal and chase you at the same time nor can he farm unless he has something like sunfire cloak.

I dunno, maybe he backdoors down two towers before you can do anything. Then you get to him using homeguard boots. Take him down past half life then he runs away, you use your root/stun, catch back up and right as you land what should be the killing blow(s) he meditates up past half or to full depending on stuff (your dmg his build.) It's just really too much in a situation like that.

He pushes a lane and doesn't get punished for over extending unless your TEAM successfully attacks him...which can cause other problems >.>

In a fight where you can't afford to focus the carry while the carry is chunking your team...
In a fight where a squishy with nothing to offer but damage can initiate...

can you honestly say that you have any business teamfighting in this scenerio? Something here isnt in your favor and your team just needs to gtfo.

stopped reading here, are you saying yi can 1v1 two towers before your team can do anything? Because he can only do this as fast as minions move otherwise which isnt too fast even if alphastrike could hit and autokill 6-7 minions at a time. Even then if he's AP he does no damage to towers. Yi is not the one to blame here for your failure to stop/prevent splitpushing. especially when wards, promote, fast boots, and time are at your disposal like never before.

If you dont mind me correcting you CerealBoxofDoom

Ap yi can do massive tower damage, but the problem is, he doesnt have the AS to back it up, his ult gives a good amount, but not enough w/ AP to make it as fast as an AD Yi.

Remember, when attacking structures, you either do +Bonus AD or 40% of AP extra to towers, whichever is the higher number, though a lich bane on Yi, and he can smack the tower pretty hard.

*Edit* so with that being said, a 500 AP yi that pops his WuJu style, the extra AD from it wont factor into tower hits.

But I do agree, there is no way that yi can get 2 towers w/o your team responding, unless you all just got wiped, or you are too busy to realize that yi is trying to backdoor you, in which case, either base race him (which you will win) or get an objective that he cant by himself (dragon, their/your jungle buffs, Baron)

I agreee, I dont think AP yi is overpowered at all, sure he has a heal and an alpha strike but thats really it. Just shut him down, stun him when he heals, silence him when he heals, knock him up when he heals, its really not that hard. As for his alpha strike, banshees veil works well. If you're playing an AP yi your team should know to try to stay fairly spread apart with the adc in the back, this way his alpha strike will do minimal damage to the team.

Not to mention, Veigar drops blue poops all over AP Yi.
