I hate arenas but BGs seem ok. Im assuming unholy is the way to go. Also, in BGs should we stack the pvp gear or just wear enough to get by?
When it comes to just doing BGs, go with what you like most. Blood has amazing survivability, Frost is, in my opinion, very fun in BGs, and Unholy is pretty much the go-to spec for DK PvP.
My Armory Chuck Norris ftw
It depends on the BG
