A lot of these champs aren't among the most popular ones but that doesn't mean they don't deserve a skin. Champions like Akali, Lux and Ahri are getting a skin every few patches while these poor bastards have been waiting for years and I think it's time Riot should give some attention to them too even if they don't sell as well.
