Zix 101

I have thought of a game type where 6v6 go at it. But when a red kills a blue or vise versa they switch teams. So you keep playing until there are 12 red's or 12 blue's left and no one else on the other team. This gametype can be pretty unfair when it's 1v11 so I think giving the last man standing a rocket launcher and an overshield or something like that would even it up. Do you think this gametype "Extinction" would be a good idea for halo 5?
