Why aren't there anymore Riot Skins?

skins in general are complicated

often they hold off on new skins for a Champ until they are due for an update, and even then there is no 100% guarantee

as for skin series/lines that's even harder

choosing which Champ might fit into a skin series can be problematic, especially since people here on the forums/reddit might disagree with them.

they also want to make sure it will sell, making a skins for the sake of a skin doesn't always go well, as it could fall flat, or not be on par with other skins in that series

Well they are supposed to be expanding on older skin lines this year, so who knows, that could be one of them!

I think its because people didn't really like them, personally I was never really sold on a skinline of champs in just Riot gear

Those skins were generally pushed out for promotional events like PAX, to which, Riot has stopped going to.

I want more officer Skins!!!! Currently only Officer Vi and Cait as far as I know >.>
