fiora has counterplay here i'll list it

Actually the counterplay to fiora is disengage. Not necessarily in a 1v1, but in a 5v5 you can screw her by disengaging hard when she marks someone with her ult.

the counterplay is to outmaneuver her to protect your vitals, play around riposte and disengage her ult.

the counterplay to vayne is actually jackshit, since she has not a single ability in her kit that you can play around.

there is a difference between a champion being strong and a champion not having counterplay. it would be just as dumb to claim that draven doesnt have counterplay. hes just so overtuned that it doesnt matter.

You missed the Memes & Games section

Protecting vitals. Abusing her q (only gap closer/escape) cooldown. Not throwing all your abilities into her one defense ability. Avoiding second e hit. Disengaging/ kiting when ulted. Buying grevious wounds to destroy her sustain. Out rotating her with literally every champions better team fighting. Out pushing her with literally every champions better wave clear.

But you're only at a low 40% win rate, so you must think you should win every 1 v 1 by pressing all your buttons and if you don't it's because the champion is broke, not you getting our played, right?

Anyone who says (champion) is broken is just salty. You deserve the downvotes.
