Heya all, i'm a discipline priest starting back into PvP. Haven't done PvP since the arena system was introduced. But finally decided i'd like to get into it. I'm just looking for advice on how I should gear and gem, who I should attempt to partner with and what the best method to go about getting the gear is (grinding BG's or emblems!).

Also looking for some help on how much resi i should attempt to get before starting to do arenas?
Currently have 0 Resi and no PvP items!

Thanks in advance! ;D
(I have googled this but get no recent results, all from 3.1 patches or earlier.)
