Now that Xûr has sold light beyond nemesis, there should be no reason why warlocks (myself included) should not be able to have full health at Crota, on hard. Even before, there was barely any excuse, but now there really isn't one. If you don't have it, buy it. It's one of the best warlock exotic armor pieces Edit 1: I was saying there are no excuses now for people. I wasn't saying there weren't other helmets, and I wasn't saying that there were no abilities to be able to heal (I used life steal even before i got this helm). But now, people have absolutely no excuse in CE hard. Its as easy as picking up an orb.
