It's her splash

I realized, thanks to a certain meme, that the problem is in fact not Qiyana's design. The design is perfectly fine, and anyone trying to say she isn't unique is providing no actual example for comparison because... they can't. Her clothes and jewelry actually don't look like anyone already in the game or in other mobas.

But her splash is. It's a little off from the regular style, and they've done a good job of removing "just standing here with my weapon" splash arts from the game. But that's exactly what she's doing. Just... standing there. No dynamic action, no cool pose, no interesting angle.

That is the actual issue.
