Twitch Way Overnerfed
He used to be my favorite AD and I still find him the most fun to play. However, his laning and general playstyle is too dangerous to be a good choice in ranked. I think this is very unfortunate because he's a pretty cool and unique champion.
Twitch currently has the LOWEST win rate of ALL ADCs in Platinum+ (http://champion.gg) so it's not just a matter of him being hard to play. At least one of his many nerfs should be reverted. He was mainly a FoTM after his visual update and people just didn't know how to react or refused to adapt (pinks, oracles, more AoE damage, not clumping etc.). Objectively, I don't think he was truly OP or it was only slightly so.
Although, I have to say that the biggest nerf comes in the name of his ultimate's new name.
