This is so *********** dumb. I can manage to get to each of the terminals and disarm them without dying, but somehow, even though I timed how long I had till each one reactivates when you're disarming the vault, and saw that it gives you about twenty seconds, I still couldn't manage to actually disarm all of them in time. I don't give a **** if it's designed to be done by two players, I like to do this **** solo. So in cases like this one, where it's apparently literally impossible to do it on your own, it should be classified as Heroic 3+. I don't care if it's SUPPOSED to be a social game, or some **** like that, some of us just like to play on our own.
