Lee, Vayne, Yas, Syndra players, we KNOW what your counterplay is...
We know how to counterplay your champion, we know they aren't necessarily OP, we know that not everyone who plays them are toxic.
But the fact is, we are still going to ban them, hate them and post about them. You know why? They are just miserable designs, miserable to play with, miserable to play against. They could all be in the dog house for stats, we would STILL ban them. We play the game for fun. But you know what happens the second I see one of these champions? No, it's not that I think "They are OP! We cannot win." It's that I think "Oh boy... win or lose let's get this over with so I can get into a fun round."
The champions are just misery. Sure, this also applies to some FotM champion during their height of being OP, and some people have specific champions they specifically hate. But by the rate of bans and complaints, these are the champions I see the most hate towards. And it isn't because we "Don't take the time to learn how to play around it." It's because the game is about having fun, and playing against your champion just isn't fun in any sense or way. I'd rather lose to Illoai or Katarina than win against Vayne or Yasuo.
and against

as a melee
is pretty bad too.
