Idea for Featured Gamemode

I kinda always thought that the 2 team concept was quite limiting to the League of Legends featured gamemodes. It would be really cool to see league implement a multi-team system. Something like a 2v2v2v2v2.

Personally I'd like to see it on a dominion type map where everyone has their own spawn platform. Then they're release into a jungle of sorts to get buffs and try and pick off enemies. I don't know how easily it could be made, but I'd really like to see a gamemode with more than 2 teams. My personal preference is towards a 5 team's of 2 concept, but of course it could be broken into several other types. Imagine a 3 team twisted treeline! I don't know... DISCUSS
