Found out something interesting while on the Blizz forums, http://us.battle.net/forums/en/wow/topic/20748565441 now take what is said here with a huge grain of salt, but if what is says is true then some professions will be gated behind the need to do PVP..
I have no official Blizz info on this only what is said above, but will be interesting in why Blizz felt the need to shoehorn people into PVP again..
