LoL: Going back to your Roots (Custom games)
I would like Riot To implement a Map editor (which is where you, along with DOTA, were forged in the fires of late night map editors on WarCraft)
Players can create custom scenarios from 3 vs. Minions, where you have to fight off minion waves and see who can last the longest, or a game mode where players can buy extra minions to send to lane... Custom maps!!! I think this will revitilize your game for many and sort of put an ease on the stress of competitive play..
