Summoners Rift Vanity Skins
I feel that adding skins for the map such as winter (already there), beach, jungle, mountain, Chinese, city, future of prototype, ect. There is a game on steam called "Town of Salem" where you can get new map skins and it feels like a completely new game!
Pros: HUGE PROFIT: honestly riot, if you did this I'm sure everyone would want to purchase one of these Removes to a degree repetitiveness of summoners rift with new look Champ skin environment interaction (Pool Party matches beach skin ect.) Player customizability and more....
Cons: Possible longer loading times (I'm assuming) umm, you can fill this in if you have ideas
Thanks, Joe P
