Papercraft Anivia Q looks much smaller than any other skin...
And it has no outer border that shows the radius of the skillshot like any of the other skins. It's pretty annoying when I can edge around it when someone plays the default skin, but can barely see it coming on the Papercraft one.
I have to play with low effects quality to keep my FPS at 60 in teamfights, so maybe that has something to do with it. Even so that's pretty pay to win if you ask me.
