Great, you're reduced to insults already.
Why should any other players loose content because of your, and your groups preferences. My personal gamer ethics, and the design of the game, allows for each of us to make our own choices, and requires each of us to live with the consequences of those choices. Your choice to limit yourselves to a single mode shouldn't be allowed to influence my available choices. Players being completely equal balances the scales, and is more important than a dubious parity between the modes.
The idea for separate BGS's is generally rejected for feasibility reasons. The entire game is based on the one BGS state. Having multiple states of the game would overly complicate things, and be costly. It is also pointed out that the modes are not separate servers, but rather matchmaking filters. Finally, if cross platform play, where there is no chance for interaction, is acceptable why is cross mode play so deplorable?
