that's not true at all. in fact, quite the opposite: she now has a host of counterplay options, while still being rewarded for executing properly. granted, her rewards are probably a bit high at the moment, but her core kit is good.
old fiora's q was a point and click. unavoidable in every aspect. same with her ult, which also made her untargetable for the duration. her old parry, while only blocking auto-attacks and on-hit abilities, had a fairly long window and didn't hinder her movement or even interrupt her previous commands. new fiora requires a lot more precision and position, and she's nowhere near as good in teamfights as she used to be with her old ult + hydra.
