Fizz's excess power: Built in healing debuff/reduction... that stacks on top of a dot and stacks in addition to ignite with no DR
A better version of Vlad's trollpool with the ability to jump certain walls and no hp cost... in exchange for a trivial amount of mana past the first rank of the skill
Can Q through minions to escape, as if he didn't have enough mobility already-in addition to being able to walk through units by having no collision
Ult gives vision upon initial collision, even prior to the shark actually activating
Massively unjustifiable base damage that scales absurdly well with sheen, itemization is meaningless so long as he gets 2 or so core items
Decent AD in addition to AP, base stats are excessive for no real reason, on top of everything else
A borderline ranged auto attack radius, despite being melee, as stated in the OP's post
Forgiving mana costs on all abilities despite using mana as his resource, and despite the power of his abilities themselves (not even getting into that...)
Q also applies on hit effects, INCLUDING HIS W'S ACTIVE
Q's on hit application does not diminish, meaning all on hit effects actively apply simultaneously, stacking
GUT FIZZ
this champion has flown under the radar for soooo long and is contrary to everything a balanced champion should be, he has always been, and still remains tall standing as, one of the most overpowered champions in the game with a myriad of excess power that simply doesn't make sense and is just stacked on top of his already stupidly effective kit for seemingly no real reason other than to give people freelo.
But of course Fizz mains will defend their broken champion who is immune to nerfs to the death, even though they know just as well as anyone else that Fizz is not balanced whatsoever, just as Riven mains did during her OP phase. GUT FIZZ
