I had an interesting idea for a game-mode, although pretty random but I thought I'd throw it out there.
You could call it "mercantilism" or "banks". Two or more teams hold a storage of "money" which really translates to points. There is a set time limit for the game, and during the round each side attempts to steal as much money from each other as possible, while not losing any money themselves. I think it would make the most sense if killing players gave no points, but you could pick up stolen money from their dead body like you can flags. It would be a lot like capture the flag, except multiple people can steal money at once (but only a certain amount at a time), and at the end of the game you are awarded a sum of points equivalent to that of the money contained in your bank's. (And you could set how many points banks start out with.)
That was just a random thought, and I really don't know if I would ever use it but it would be interesting to play.
