Imho FIORA has the least counterplay of any champion. That stupid vital is almost always pointed right at her. There's really no cool down on it. She does basically all true damage percent max up and has great engage/chase/escape. I have yet to find a champion that counters her and beats her in lane (maybe I'm bad) in a teamfight it takes a concerted effort to eliminate her with plenty of CC. If they have any other moderately fed threat you're going to have a bad day.
You can't build to counter her. You can't win burst trades. You can't win sustained trades. She gets to choose when the trades happen. She's hard to CC. There is no limit to her scaling. That ult heal is just gross (i don't know why people don't just target the out of position player that's getting nuked in a teamfight that dies to just pop it for the heal.)
Honestly she makes DEVOURER jungles look like weaklings. Hell I've even seen tank FIORA do absurdly good.
all I can figure is Quinn beats her in lane, or maybe NASUS can win. IDK but when I see her in my games I whimper.
True Fizz is just disgusting and not fun to fight. The worst part of fizz is he can miss every untsrgeted ability and still kill a squishy if he maxed q. If he gets a little ahead he can turret dive poke you twice (taking no damage) and then kill you under turret.
Imho a good nerf for fizz would be making his E not block turret shots.
