Yi is a champion that makes people in low elo want to fucking kill themselves. He just needs to get to you and rightick and he gets a kill in a teamfight and the you is good mechanically even though all he does is rightick, good luck stunning him because he'll just q every skillshot and he will get a pentakill. That is until you get to high elo. At that point, everyone knows how to beat yi. They'll go Jax, xin zhao, or Warwick and stun u the moment you reappear from your q or just straight up fight you and kill you if they picked one of those 3. What o does your stop being useful to where you actually have to play something like Elise or lee sin.
