Primal elements being camped hard by overwhelming enemy side.
Especially primal air, the people farming them have memorized the patterns and spawn points of the air elementals and are guarded by an army of people watching over the farmers most of the day if not all.
Even if you were to bring your friends to gank them, the respawn zones are pretty near so they just respawn back and it just ends being some sort of improvised warsong arena for the control of primal air.
Just in general, has this been a problem in TBC? i started this week playing and i've enjoyed a lot the game, but i just have trouble understanding some of its mechanics, i don't mean it as a bad thing, everybody has to get their profit after all.
