It's funny how you guys discuss pages over pages about your social theories and server "trends" while in reality the cause of the issue and the solution are so simple:
Fully decked out PvPers don't need honor. There is no incentive for them to win BGs quickly and to care about objectives. So they rather just PvP instead.
The result is the HK farming meta that we can experience right now on the Wotlk high gear bracket.
BGs on the other brackets are played in a very different and more healthy way because players need the honor to gear up. On TBC and on the Wotlk low and mid tier bracket ppl actually care much more about objectives and there is much less braindead pvping than on Wotlk high gear bracket.
So whats the solution?
Very simple. Give fully decked out pvper on Wotlk a incentive to win BG. Make the amount of BG wins the E-Pen*s instead of the amount of HKs.
That can be done in many ways but it will requires custom conent and developer reccources:
1) rated BGs with vanity rewards.
2) Seasonal titels for BG wins
3) BG wins scoreboard instead of HK scoreboard
