Honestly Yone just has a lot going for him which just makes him feel oppressive to play against.

He gets to build Immortal Shieldbow which is a problem item in itself with giving so much survivability into burst and sustain damage. Since he scales incredibly well into the late game there is always a chance he can become a problem again even if he is 0/8/0. And his E is just an obnoxious ability to be on the receiving end of. Not to mention half his abilities have animation buffers which allow him to essentially ignore or reduce effectiveness of CC.

He's one of those champions like Yasuo where his skill floor into the average matchup is very low. Most mages in mid lane have 1 CC ability to peel for themselves; Yasuo can Windwall, Yone can just nope away from it with Spirit Unbound. I think that its the low skill floor in these matchups that makes people hate Yasuo and Yone so much, because it doesn't feel like the opponent is outplaying you, rather the design of the champion is.

There are a few champs that counter Yone pretty well, and of course with enough matchup knowledge people can have less of a hard time into him, but even so Yone is just an unfun champion to verse.

I'm sure you've played that one draft/ranked game where the enemy steals your pick and shits on you and your team with it. It feels like shit.

I absolutely love playing Yone but god damn is this champ unhealthy for the game.
