After browsing boards these past few days, it seems that Fizz players just love wallowing in self-pity, in that they can only lament on how these changes will destroy Fizz. I don't hate Fizz at all, but I will not deny that Fizz is overpowered. He's one of the best picks now, and dominates nearly every game he is in.
This is supposed to be a nerf. Many champions get nerfed with absolutely no compensation at all. Let me repeat, this is not supposed to be a beneficial change. It's purpose is to make Fizz weaker, specifically Tank Fizz, which nobody except masochists enjoy playing against. And it seems Dr. Mundo isn't META now.
You aren't being persecuted. Fizz will not be gutted. He will be perfectly playable after these changes. If you are truly a Fizz main, you will stick with him and keep persevering. I speak from experience. My main has been sitting under 45% win rate for over 2 seasons, and despite all that, received multiple nerfs to every basic ability until he sat at 38% just recently. But I don't bitch and moan about it, I just play, and I'm doing fine.
