People always say that that's how you should counter Fiora, but how does that work? I'd understand if you could turn to move the vitals but since you can't your only option is to wait for it to fade away and hope that the vital isn't facing her when it respwans.
If you get in range and there's a vital facing her, back out of range and come back, you'll get a new vital.
Also do your best to save things like cc and bait out her Parry.
Stay far enough away to keep her from getting to the side that has the vitals or stand with the vital close to a wall, especially when she ults to keep her from hitting all 4 sides. You can back out of range of her passive as well to reset it to a different side if it is on the side facing her and you are being zoned, and during her ult you can use QSS to remove the vitals.
Essentially, there isn't any way that doesn't put her at a free advantage. You either back away, give up cs, and hope it reappears behind you, or just let her delete you. Her passive means she always has the advantage; and no, there is no way to play against it correctly.
