For the last day and a half I have been hanging out in the battlegrounds quite a bit and I’ve gotta say, its been awesome. If you haven’t tried it yet, I strongly recommend it. The build I have been playing with is http://www.wowhead.com/?talent=LZhxZVfzrgbdibIzsGo.
Admittedly, I have a pretty big advantage because I can wear 4 pieces of T6 and 4 pieces of gladiator gear, but even without the T6, prot can be very potent. I am wearing 50/50 pvp and pve gear so my resilience is only at 260, but it gives me 25.5% crit and 1839 AP unbuffed and 15.3k hp. But with talents my devastate, shield slam and heroic strike all gain another 15% crit for 40% crit on my big damage abilities.
With those kind of offensive stats I have as much burst as an arms warrior and with shockwave, imp revenge, concussion blow and imp disarm, I get a ton of control that you don’t get with arms. Add in warbringer to break snares and I am also much harder to control than an arms warrior.
Before the 3.0 changes a prot warrior could usually kill any other melee class but it would take a while. Now its a joke. A prot warrior just destroys other melee. And since a prot warrior can break snares, you can kill most casters as well. The only thing that gives me trouble is well played hunters and healing priests and shaman.
I am having so much fun with it I just had to post about it. If you haven’t tried it yet, you really should.
