Expanded Custom Games

I have been playing this game for only five years as of now, and through all the salt i still find enjoyment in the game. There have been some incredible ideas to spice up League of Legends for older players, such as the rotating weekly game mode.

I think i have an idea that will spice up custom games a little more.

My idea is to make Custom games truly 'custom' in the sense that the customizable content is expanded to being able to customize minion/player stats, creating custom debuff/buffs, making a game have a time/life limit, and adding aspects from Nexus Blitz to your custom game as the host.

When it comes to maps, they should bring back the Dominion map, and keep using the current rotation of maps (summoners rift, twisted treeline, and howling abyss)

I think a major problem that comes to my mind when in relation to this idea is the fact that if it's too entertaining, people will simply just stop playing normal games.

Tell me what you think.
