I think nerfing the percentages but increasing the scaling might fix her.
i think this really is it. It just seem's like there is no real defense against her. Stack magic res, doesn't matter that much because I stack mpen. Stack health, great, cause her stuff scales off health anyway.
That's also bad, since she doesn't realy snowballs unless she is insanely overfed. You cant do too bad but you cant do too good either. But giving her flat scaling instead would take away her uniqueness.
I had to lane against her twice in row yesterday after never playing against her and I can honestly say that I have never been more annoyed by any champion as much as I was after playing her back to back. Her Q is a joke.
