Just curious, is there a recommended updated Unholy PVE guide? I've barely touched my DK this whole expansion and want to play around with the class a bit more and wanted to give UH a try.
I've seen some vids on youtube but some of the information between what I see posted here and on the various vids seems a bit conflicting (Haste vs. mastery, extending diseases with Festering strike vs not using it etc).
Haste varies by fight, the more you can AMS-soak the less haste is worth. I sit at about 4k-ish haste and usually have little downtime unless there's nothing to soak. Festering Strike should mostly be used on only B/F runes, altough there are a few fights (Thok comes to mind) where extending strong diseases with death runes is worth it.
