Ward skin sales

I think it would be a good idea to make ward skins go on sale. maybe every other week and not as big of a sale but still some sort of price cut on one ward skin every other week doesn't seem too bad. Not many people have ward skins and publicizing price drops on one of them once in a while would definitely give more attention to that. I understand that there are only so many skins for wards and that they would cycle through all of them very quickly in comparison to champion skins but to be honest how many people have multiple ward skins? I didn't have a ward skin until the deadfall ward came out. Every once in a while I think about getting another ward skin but for a lower price I can just buy a champion or another champion skin that is on sale. Not to mention it would probably increase profits for riot a little bit. Just another shower thought for the world
