Don't give up... it still drops in DF and is easy to solo. Killed the first boss on Mythic, picked up a key, opened the cell to access the hidden passage, clicked on the bucket, killed Gol'than, looted the corpse and immediately logged out. On logging in about 30 minutes later, you will be at the location of the first boss (who doesn't reappear) and can repeat. I cycled between alts until it dropped on the 49th attempt.
