BF3 just got more competitive now also, you can now choose your teams from a roster to allow a clan match within a controlled environment. "With the Match settings in place, players then select the rosters for their teams from their list of friends and platoon members. A team leader for the rival team is assigned who in turn also chooses a roster for the opposing team."
