I was just tanking Dragon Soul Raid the first bosses thinking of nothing bad, then suddenly noticing quite often these shaking numbers at the incoming damage... naming the globules trash mobs and that lieutenant before hagara hitting me for 120k critical resulting in my death. So I don't know whats wrong I skilled imp. blood presence for crit immunity and i am nearly convinced that i had not forgotten to switch it on because then thread issues may have occurred on the previous boss fights/trash pulls. So is this just a bug or am i missing something here?
If you check the death knight forums on the official site you'll see there's a few dk's with the same issue, apparently imp blood presence is bugged and the work around they found was to swap presences upon zoning into places
