New Custom Game Mode Options

Hey riot, recently iv'e been having fun playing with my friends in custom, just dueling. However there are three of us and we are always forced to play 1v2. Now i assume everyone has played halo, and if you have you know the game options they have. One that really sticks out is how in halo, you can pick the number of teams in each game which surprisingly you cannot do in League. I know it wouldn't be hard to add in the option to league, maybe on the dominion map? Each team could spawn at a turret and/or just spawn randomly on the map and you could just have a fun deathmatch with say five people all fighting, sorta hunger games style. I would love to see this as a custom games feature and i don't care if it would destroy farming.. just a fun option for friends to mess with. Please take this under consideration. Duces
