Not sure if this has been brought up or not but after reading around on the Gearbox boards, it seems that someone did an experiment on PC with the Vault Hunter Relic. Set it to like +10000% rare loot or something and it basically just removed white guns and replaced them with green ones, while having no apparent effect on blue, purple, or orange drops. So if any of you guys are still clinging onto it, you might as well ditch it in favor of something more useful.
Thanks. I ditched it a long time ago and felt kinda bad, but now I don't.
