Riot should think about possibly making "evolving" skins, at least for Void and Isles Champions.
Sorry if this was posted about before, but as a fan of SMITE and LoL I was really surprised and excited to see the Archon Thanatos "evolving skin", and was thinking to myself it would be quite an awesome thing if Riot decided to try their hand at the concept.
The costs of those types of skins would most likely be far more than current skin prices, but I do feel it would be something that'd interest a lot of players and possibly create more revenue for Riot.
I mean imagine if someone like Thresh has such a skin where he starts off "normal", and over the period of the match starts to grow a little bigger and more demonic looking (more souls floating around him, more menacing weapons, etc...)
