I've been searching for quite some time now, and I've yet to come up with anything definitive. Mismatched and misleading information has only left me more confused than when I started.
As DW frost, does mastery outweigh haste, or vice versa? I've also seen some that completely ignore Obliterate altogether and some that argue otherwise. The same for keeping diseases up. Is Obliterate a key ability? And outside of Unholy do I need to worry about 100% uptime on diseases?
The general vibe I've gotten so far was to spam Necrotic Strike + Frost Strike KM procs, but should I pick up Rime etc for Obliterate? What abilities should I not be using?
