PBE Nerfs are far and away uncalled for
If Fizz is nerfed in the way he is right now on PBE, he will become borderline unplayable. He already has a hard enough lane phase, and the melee range nerf will make it even more suffer-able. Really though, the cooldown nerf on Trickster is what will do him in. His mobility and ability to dodge spells are what he's all about. What's the purpose of even playing him if he can't remain "slippery" throughout a team fight? The only reason he has started to become better is because he can actually itemize towards optimal CDR items. Fizz isn't even over powered right now. If anything, he's an occasional competitive pick who incites flavor and diversity in champion select. Nerfing Fizz would not only be a huge step backwards in the sense of progress, but it would detriment the variety and diversity that should always be seen in competitive play.
