I think on the countdown game mode, there should be a little stop watch. If the attacking team gets all the cap points in 4 minutes, then when it switches and the other team is attacking, it should say 4 minutes and be counting down so all the players know how much time they have left to capture all of the points. I think that when the opposing team hits that 4 minute mark, but continues to try and cap, the game should end right there, instead of letting the game finish only to find out that they didn't capture all of the points in time.
