We need a Free For All mode

I know I'm not the only one that has thought about this. We need a game mode on a map maybe similar to Dominion where we have a set amount of champions that can all fight each other at the same time. I believe that Riot has thought about it but they like the idea of a team game but at the same time there are lots of players that like to depend on themselves. This could introduce new items or even a new map to freshen things up a bit. People would also get a chance to show there skills without having to rely on others. Riot has been making all these new games modes but i think they need to finally breach out into solo play.
