Fizz with 45% CDR.
What idiot thought this was OK. Fizz's troll poll needs a longer cooldown in the next patch. If anything is anti-fun, it's playing against a fizz thats invulnerable more than hes not and does 600 damage every 4 seconds. There is little to no counterplay oppertunities in a 4 second window when the troll has a zhonyas and team next to him.
