OP is not the only one who has Trypophobia. I do as well.
https://en.wikipedia.org/wiki/Trypophobia can give you more information about the condition. Read all the way to the end. The part about anxiety and nausea.
Essentially the shape, spacing and uniform color give me anxiety and I become nauseated. Her e ability in the skin is not nearly as bad, fyi. The response is still present, but not as bad.
If the visuals aren't changed I will legitimately have to dodge every game with her in it. If that's how it has to be, I understand. Also, I understand that someone else may have phobias/discomfort associated other champions. In my opinion that doesn't invalidate my own or OP's. It all sucks. Not saying this sucks more than someone else's, just that it sucks and I would have a less optimal experience than I used to. Also, from my very limited perspective, fixing this would be relatively easy. Not to diminish the hard work it would take, but it would be easier than say removing a champion.
Thank you for reading.
