Fizz
With the changes to his w, fizz's winrate has dropped** 4%** since the last patch. I'm surprised I haven't seen posts about this. His w is garbage now. It's like a weaker version of his previous w with an aa reset (which is pointless past early game on ap champions hurray.)
Thanks for the random revert/nerf that I saw no one on the boards asking for.
Harder to see on this graph, but it's not only champion.gg that says this: https://www.leagueofgraphs.com/champions/stats/fizz
