Free for all (gamemode)

I don't think I'm the first one to come up with this idea, but I didn't find a thread like this yet. So, what I thought was, wouldn't it be cool to have a free for all gamemode (like Ascension or Nexus Siege)? There would be single summoners or maybe groups of maximum 3 people fighting versus many other players (or little groups) in a big arena, like that one Ascension uses. If there really would be only one person versus everyone else, there might be a problem with teaming, though. The small groups I mentioned before might solve that. So, I hope i could make my idea understandable, and I would really love to see that kind of gamemode in the rotation.

(I also hope this is the right board to choose ^^)
