Fiora's passive should reveal weak points at the position relative where Fiora is facing the champ.

i feel like if the passive is just facing fiora it would be easy to abuse it makes more sense to do a random part of the champion other wise it would be pretty op all u have to do to trade is walk up hit and run

Problem with that is the fact that it deals %hp true damage. It gives her a lot of power in trades. But at the same time her opponent can take advantage of it.

Making it something she can control would be far too overpowered. People are already upset about the %hp true damage.
