There is an abundance of loot, just not different loot. I go back and forth on the random roll thing. Mostly I think it is the same since normally I would look at the drop and see perks that kill the weapon and delete. So random rolls are better for 10 or so seconds and then the delete is the same. I am scarred from the chase of the perfect Imago Loop and Grasp of Malok, 3000 hours and never got close. More disappointment came from that than knowing I have every legendary and exotic weapon in the game at the moment. (Well other than the Trials stuff since I am a scrub)
