New Mode - Non-Static Teams

I think it would be cool to have a mode where, there is some objective and when your team captures it, teams change! Like the old game, "King of the Hill". So you're never stuck with just the people who queued up, if they are bad or what not, as soon as the other team captures, the friend that was standing by your side is now maybe your enemy. It would add so much chaos to the game, it would be hysterically awesome and strategy would be changing constantly.
