Tank Fizz...
So, I haven't seen any tweaks for fizz on pbe and I think Meddler admitted that him alongside tankko were an issue.
What surprises me the most about this is Fizz' cooldown on his ult, I just saw a fizz using his ult on bot, run around towards mid and use it there again... I think the dmg amp is what allows fizz to build tanky but the rest of his kit has quite high damage as well.
How should Fizz be tweaked/nerfed?
