I had been leveling her up as a tank to pair up with Lori's healer, because a tank and a healer can generally get DPSers for instances.
But lately, we've been hitting instances with another warlock and bruceb's Protection paladin, and sometimes also our guild leader's feral druid. I'm sure it makes us an extremely rare group to have this surfeit of tanks.
But this is more tanks than we really needed. Bruce is having fun with paladin tanking, and it will help our guild more for him to have a capable tank character than it will for me to have a second capable character. So I've been working on DPS for a while.
I tried a 41-point dual-weild Fury build that i'd read from the Elitist Jerks forums. It was okay. But it involved a lot of waiting on cooldowns for Bloodthirst and Whirlwind, and making sure that Rampage was up at the right times. And also (and this is admittedly a small point), I found "Bloodthirst" sort of abstract--I couldn't imagine what it would feel like to perform Bloodthirst.
When I did Ring of Blood, I tried another experiment: I took the two-handed axe reward, and respecced to a two-handed Arms/Fury build with Improved Slam and Mortal Strike.
I hated it. I hated it so much that I respecced after one night. I had a lot of trouble timing my Slams appropriately, and I was almost always so rage-starved that i was missing out on a lot of special attacks.
But I noticed something: there are a lot of nifty DPS talents deep in the Protection tree, such as One-Handed Weapon Specialization, Focused Rage, and Vitality. It took me two respecs to get it right, but I'm working towards this as a dual-wield Protection DPS spec: http://www.wowhead.com/?talent=Li0czhZVZcitoI0zkxst .
I am loving it.
My DPS may not be perfect, but it's very good--in our most recent run through Auchenai Crypts, I had a slight lead on our warlock for damage dealt, until we got into all the AoE fights in the last room. My DPS for that run was about twice the DPS I had managed with my 2H Slam build.
I hardly ever have rage problems with this build. Anger Management, in particular, is a huge help for maintaining a big head of rage. (One rank of Anger Management turns out to be more useful than five ranks of Unleased Rage.) I've been learning to add Heroic Strike as a rage dump when I get more Rage than necessary.
And I feel I contribute more utility. I'm providing Sunder Armor to boost the DPS of all the physical-DPS folks I can certainly off-tank in an instance; I also have enough tanking talents that I have complete confidence that I could tank an instance smoothly. This is particularly important because I believe that the most effective way to gear up a DPS warrior in PVE is to tank instances and pick up DPS plate that no one else wants.
And lastly, DPSing with this spec is pure fun. Fury had a lot of waiting on Rage and cooldowns--but nothing has the raw fangs-bared savagery that I feel playing this spec.
