my group couldnt do him, he simply one-shotted the tank at 30%. no enrage, no storm, no rocks, nothing. Just bam, oneshot. (no combat log either to check what it was)
Seems bugged, either enrage buff doesnt show (in which case, RLY short enrage timer), or there's another mechanic thats bugged. Gear can't be the issue (i tanked all of EV and Karagga's and we killed all bosses except SOA and bonecrusher).
