@Riot, Do you ever think that it's interesting that Xayah has Fizz's trickster...but it's her ult?
Really think about that for a moment. Both Xayah and Fizz have pretty much the same move. They both make themselves untargetable and immune to everything for a few seconds, while doing damage. But Xayah's is her ultimate. Which has like a 1:50+ cooldown. Fizz is like 10 seconds.
This means that having a move that makes you untargetable while doing damage for a move that's MADE for outplaying your opponents is a pretty substantial ability and is incredibly crucial and is also disgustingly powerful. Could you imagine if Xayah could do that move every 10 seconds? That would be absolutely BROKEN..... 
We all hate Trickster. It's stupid. There's no counterplay to it. There's nothing you can do about it. The only counterplay to it, is to kill Fizz before he can do it. It's made even more unfair when you combine it with Zhonya's. You can hop once, zhonya's while Fizz is on his trident, then hop to a safe spot.
Riot. I give you credit for trying so hard to make Fizz fair. But as long as Trickster remains in his kit. That will never. Ever. Ever happen.
The moment you get rid of Trickster. Is the moment when Fizz actually will become a fair champion.
