Same conclusion I am at.
I am using 4 piece bonus from belt, boots, wrists and shoulders. I have Brutal Chest and Gloves, Vengeful legs, though I almost rather use my
sunwell crafted gloves. I am working on the s4 helm. I have the badge pvp cloak, guardian neck, guardian ring, 2min pvp trinket with 20 res, I use
hyjal ring and
Tome of Diabolic Remedy.
Had a wonky arena where we managed to kill the Pally on the other side just as the warrior killed the Hunter on my side which left me with 800 mana vs a full s3/s4 warrior. Managed to kill him without too much of a hassle. Also had a couple matches where burn teams have tried to take me out and I have lived.
