Today's build is a 53/3/15 build, Haunt/Ruin with Improved Imp. The imp is the affliction pet of choice at the moment, mainly because of felhunter bugs, along with a boosted imp mana regen rate which allows him to never go OOM in most raids. For the rotation, see my previous blog post on affliction raiding. Below 25% on a boss, I use drain soul as my filler, and I drop immolate from my rotation. There are a few points here or there that can vary in this build. However one thing I must stress is that once you're using decent gear, any 1 point in ISB is better than 1 point in Molten Core.
It probably goes without saying this is one of my favorite builds. I was able to pull 5700 dps on patchwerk last night using a Doomguard, though we had a bit of lag, so I think I could have done more. (Oh what I wouldn't give for one lag-free night of raiding these days) This build is also probably one of the most difficult specs to raid with. It's a complicated spec that requires absolute focused attention, the use of DoTimer, and coordination. Blizzard is going to be simplifying this spec in some way, which will be a welcome change for most. Especially considering that when the content becomes more difficult, this spec will too.
This spec thus far has been edging out the competition to seemingly be THE top dps spec. Several warlocks have broken the 6k dps barrier with this spec. The more you have to move around while using this spec, the more difficult keeping the rotations becomes. Some argue this spec loses more when you have to move around compared to other specs, but there is no way to quantify one way or the other with any certainty. But, played correctly, this spec is truly awesome.
This spec also scales far better than some might think. Haste is actually great for this spec, as it allows you to get through rotations quicker, throw more nukes in between refreshes, and ramp back up after dps pauses due to fight mechanics. It benefits tremendously from spell damage, and benefits from spirit more than any other spec as well. Simulations show this spec actually scales better than any other spec that warlocks have.
Even with the difficult rotations, I have to rate this spec 10/10. Well played, it's a kick ass spec in every sense of the word.
