What the hell are u talking about , getting people for RBGs and making them work together is pain in the ass
In arena 90% of the time u apply CC and train some poor sod till he dies while in bgs u need a damn tactic and coordination
Also not to mention that alot of arena wannabes are runing RBGs with 4 healers and FOTM dps classes which kinda ruins the whole RBG feeling...
