Enough about riven, enough about yasuo...
Fizz is, easily, the most un-fun champion to play against. Unlike Riven and Yas, he literally is not hard to play, and im not just saying that... he has one skillshot that is usually used at melee range and a simple to understand kit. His full burst combo deals literally DOUBLE the damage of tf both ratio and base damage wise, he is impossible to escape (at least yasuo's dash doesnt deal lots of damage and has a longer cd on the same target...), and dont even get me started on his e. You go in to poke him? Boom, e ult w q dead. it REMOVES HIM FROM THE GAME. for a SIGNIFICANT PERIOD OF TIME. let's sum up his kit:
You cant get away.
He has the second highest potential burst in the game behind veigar
he is immune to poke once he gets morellonomicon
he has % hp damage
he has high dps, way too high for someone with that burst
he has aoe cc
tanky just by virtue of e and zhonyas
impossible to duel unless you're someone specifically designed for dueling like jax
Weaknesses:
high mana costs
falls off a BIT late game
????? He's not squishy like most assassins due to his e, he has cc and it's aoe... hes basically a better ekko
edit: here come the downvotes
/sigh
