Every game i play with Fiora, she clicks R and kills who ever she is stop laning against. She is more broken than katarina, at least katarina's ult can be canceled with crowd control. Fiora being unforgettable while ulting makes it literally impossible to crowd control. Since she can 1v1 anyone that means that she can split push and no one can stop her. She needs A NERF.
Sion and Jax both work very well against Fiora. You just can't rush a damage item unless you are winning. Rush ninja tabi her ult procs auto's meaning its losing 10% of its damage each hit. And all of her damge is AA based.
I find Yi 10x more toxic than Fiora in solo queue because he requires so much team work to shut down.
Fun story, Fiora can totally be hit during her ult. You just can't click on her during it.
AoE damage still hits her (I die to that all the time) AoE CC knocks her clean out of it (think Annie's stun-Tibbers and Amumu's ult) DoT's keep on chipping away during it Skillshots can still hit her but it's really wonky cause she's technically dashing around while basically invis
Also 
if you feel like being a jerk to her.
But yeah, even I think her ult is boring and kinda silly. It was made before 
existed after all. Don't worry, Riot already said it's gone once they get around to updating her.
