Fiora is literally "Full retard, full reward"

10% HP vs a full rage ulted Renekton? That's not a problem when you're Fiora.

Going to take 4 turret shots at level 3 because you know your next Q dash can kill your 50% HP laner? Worth!

Just used Q for no reason and your laner engages? No problem, it's up again!

Nerf her numbers all you want Riot, the problem hasn't been solved. She could have the mobility of a turret and still be an oppressive champion.

Like literally whoever "designed" her must have been on a fantasy trip about the ultimate unfun oppressive melee champion. She's everything people ever complained about Irelia being with more mobility and sustain.
