If you wish to have a shot at getting upgrades for yourself, I'd advise against grouping with anyone from the guild Altera Pars (Alliance).
I was in SM Armory and when Herod was killed I noticed that the looting system had been changed to Master Looter. The ML told us to roll on an item and upon doing so, because I won, he opted for a new roll and before I even had the time to roll again (which I shouldn't even need to do in the first place), the item had already been given to a friend of the ML.
