Why no more Surprise Party skins?
I just looked on the PBE and the april fools skins are really nice but i'm curious why more surprise party skins haven't been made for champions that fit the idea. The one i always wanted was for Evelynn, a reference to those girls that come out of cakes at some parties would be pretty cool, i also love when champions get skins that completely go against what the champion actually is like, something about is really interesting.
Some other choices are Leblanc and Katarina, maybe you could argue for Talon and Akali as well. Basically every assassin fits this skin line pretty well because their entire class is dedicate to scaring the shit out of you. Oh and neeko, for obvious reasons.
