It's unclear if DG works for blood, because blood's version also taunts and taunt works on bosses. I don't think anyone tested it yet. It definitely doesn't work on bosses for unholy and frost.
The unholy ghoul stun does proc Sephuz on bosses as it also deals damage.
Uvanimor should be much better in 7.1.5 than now, because Unholy will resource-cap less often.
