PvE-wise. Where do all of the 0/3s, 1/3s, badass proc bows, regen, and LMC items drop? Do you basically have to go luck farming or rely on stuff like the Gaman Horn strongboxes? For a good while, I used to farm Rotting Corpses and I was pretty sure they were high up on the loot chart but I usually got pretty worthless stuff from them. Or is the secret in the trade skills?
