ive always been a blood dps dk, but as blood is the new tank spec its probably time to change to unholy dps..
So i wouldnt mind any suggestions on dps rotations ;)
There isn't a rotation anymore, now it's a prio list. Anyway you should go for something like this:
Diseases > Dark Transformation > DnD/SS if both Unholy and/or all Death runes are up > FeS if both pairs of Blood and Frost runes are up >
DC if SD, 100 RP, will overcap RP with anything else or if DT isn’t up > DnD/SS > FeS > DC > HoW.
Where you'll have to put blood boil in as you please in AoE.
You should NEVER use Icy Touch or Plague Strike, since you will just use Outbreak to spread diseases, then Pestilence if there are other targets NOT CC'ED around and you should be able to keep diseases up with FeS (Festering Strike).
For the notation used:
DnD= Death and Decay
SS= Scourge Strike
FeS= Festering Strike
DC= Death Coil
RP= Runic Power
DT = Dark TRansformation
HoW = Howl of Winter
