We completed Heroic Black Morass at about 9:20 server time on Bloodsail Buccanners on 8/8/21. The last boss did not drop the epic loot final heroic bosses are supposed to drop. He dropped a primal nether, mana etched crown, handgrips of assassination, and a glimmering fire opal. No epic loot besides a crappy gem that is supposed to be on its own drop table.
Of course I opened a support ticket and was just told “too bad, so sad”. Please fix this.
