LevelBF is going to be hosting tournaments and competition seasons and they have been doing it throughout the history of the series. they will have the best set of rules/bans for competitive play. however no one will be doing any form of competitive play anywhere until console players can control servers.
that being said, i just want to throw this out there... competitive BF is a whole different world from pub stomping. that's where the best of the best play, so be prepared. i did some competitive play towards the end of BF3 and i fucking hated it. it's not much fun getting your shit pushed back over and over and over in a round. it's just a heads up, i'm not trying to discourage anyone.
if that was something that you guys did want to do i wouldn't recommend conquest. we would need some pro chopper and jet pilots otherwise our air and armor would be eaten alive. a good attack jet pilot can DOMINATE an entire other team.
