Camping and crowding in all game modes

Someone from Xbox or EA needs to insert something that will prevent players in online from camping, crowding objectives, and traveling throughout the map in a large group, e.g. 4 or 5 players. Also, a message from me to all you people who I know have been doing this stuff: STOP IT RIGHT NOW!!!!!!!! And I mean NOW!!!!!!!!!!!! It's mean and jerky, and no one on the other team likes it. So either stop, or get kicked.
