Bleeding from passive is pretty strong, not only because of magic damage. The problem is that you can't counterbuild it at all. Building magic resistance is pointless here, and i can't see any item that would work against it.

Fiora vs Darius is counter matchup, but it is not impossible to win for Fiora. I have even got owned once in that matchup. As i said, counterbuilding, counterplaying. Skilled Fiora player is still able to win.
