At first when i saw fiora skills i said nice fiora can be played as a tank but now that she is lunched she cant tank she cant dmg even supp i dont think she can be played her ult is useles couse if u will ult somebody they will run under turet in teamfight she is useles becouse again they will flash u die like an instant so yea overall gj riot fiora is the most op champ in lol history bard can esay 1vs 1 her.
Build 
and see them try to run away from your ulty, just pop ulty>Q(vital)>Raduin+Youmu>pop side vital with E for more slow>another vital>Q last one, get heal and win trade/teamfight.
I don't think Fiora is bad at all. I've managed to carry with her pretty hard. She has a great early game since she can duel most people and lunging at their vitals and running away can poke them down hard, her mid game is strong since her heal can be pretty good and she can be built a bit tanky without losing much damage, and her late game is insanely good because she does true damage and her kit scales well with items.
u can buidd whatever u want on her she is useles i tryed all builds she cant fking win a 1 vs 1 on lane u beat early game yes but they have jungler wich always babysit them u cant hit all points couse tehy will instant flash in a teamfight if u won a game with her is just becuse enemy team was weak as fuck when i playy her im just geting mad to see how riot can fuck a champ hard
