Why is Yi a thing?
Like, honestly. Kills people in <.3s, has no real counterplay, has invincibility frames, can push W and take 60% less damage, can push R and not be kited, deals true damage... I just don't see why you haven't reworked him yet.
He either HARD HARD HARD HARD carries, or feeds. Nothing inbetween. And he's been beyond broken since the fucking start of the game, kind of like Ryze. Do you need help to figure out how to balance your game, or do you just not care?
