Arcade Xerath
Ok, Let's be honest. All of Xerath's current skins are recolors. Scorched Earth is slightly better, but not by much. If Xerath had an Arcade skin, it could incorporate so many more colors, and have an awesome model. His q could change colors each time you used it/how long you charge it, his w could change colors, his e could look something like final boss veigars q, and his ult could be controller plugs striking the area(like where you plug in the controller)
Obviously the abilities would be changed a bit more than what I have described, but ell me, this could be a way better skin for him. Like his electric-body thing could be like those lights that slowly change colors. It could be way awesome.
