I have 2 of the 3 reps tied to BGs I hope i could ask a PVP group to help me get to exalted. AV is almost exalted I know its into revereed but forget how far. IF i had to choose just one of them I would rather get Warsong GUlch rep capped i personaly find it more of a pain then av and most of the pug grouips i get are very bad (no matter if im on an alliance or horde)
For Warsong Gulch rep, what you need to do is wait until the Warsong Scramble brawl is in rotation and just spam it. Way more rep than normal Warsong Gulch.
I know of the Warsong Scrmble i giess im just hoping that theres a PVP party that spams BGs that would mind spamming the warsong scramble with me to help me pawn some horde a bit to help me get exalted with the rep.
