I was never going to use my 3-4 patches old PvP spec, so I went ahead and built this hybrid to try out. I wanted Bone Shield, Permaghoul, and AMZ, but didn't want to go Unholy. I wanted to be unique.
As I predicted, tested this out in H OK, it lacks AoE threat. Unholy gets disease damage, Frost gets HB, Blood gets bonus Blood Boil damage...but this...this has nothing.
It's a much better single-target threat spec. Basic single-target goes like this:
IT - PS - BS - BS - Oblit.
IT - IT - IT - IT > This leaves you with 2 UH runes on this second rotation. This actually seems useful, since AMZ and Bone Shield need UH runes, a good place to use those. Of course Blood Tap is a godsend for a clutch AMZ/BS too.
After that:
Gets kinda fuzzy. Still need to work this out.
Something that is fun is the Killing Machine procs. With Dirge and CotG, you will have some extra RP. Mix some DC's into your rotation when permissible to get Unholy Blight up, and also giving you another GCD to proc KM for IT spam.
KM is also very useful because it is a 30 second buff. If you have it left over, chances are you can begin the next pull with a critical IT.
Thoughts?
AoE sucks as this spec. DnD - IT - PS - Pest - ??? (Blood Boil I suppose...)
