Riot should release the game's source code to the community
It's been almost 9 years and Riot still has not given the community the ability to create gamemodes themselves. Not only that, but they removed gamemodes and expect us to settle for TEMPORARY rotating gamemodes.
It's high time that the community be able to create their own gamemodes. If the game's source code was to be released, or a program that allows for map manipulation/creation, stat. manipulation and champion+item manipulation/creation then League would continue to be a successful game.
Currently, just having ARAM and standard 5v5 Summoner's Rift makes the game extremely one-dimensional and dull. All the fun of the game has been ripped out of it due to the overall competitiveness rising. The game needs a new fresh coat of paint in terms of fun.
If Valve wants to flex their muscles like that then so should Riot.
