Since the last patch, this place got really easy. I remember pre T9 welfare epics this boss could cause many wipes. At the weekend when i was gearing my tank with lfg tool we ran this and the boss was literally dead in under a minute from the start of the combat till boss being dead, I was shocked how fast it was with a real group. With my geared 5 man team it take a lot longer due to having to run back and forth to the harpoons
Still pretty easy though.
