I was in the process of completing a step in an Exotic Bond Quest, I activated Stormtrance and so did another warlock next to me, and this person threw a grenade, melee'd us and killed us both. All while him getting out of it untouched. He was lagging, we were unleashing lightning upon his face. My friends have reported that this happens with Hammer of Sol as well. One even said he shot two rockets at a Sunbreaker, and it didn't succumb. Maybe some kind of a Super protection Mechanic? Where people who use supers are invincible unless two or more are shooting at them(in this case, those two were lagging). Bump this?
