I think the drop Levels are random on UVHM, my only Legendaries were around LV59 from loot midgets. My E-Tech mods were 59-61, and my only pearl was LV61. I haven't turned in the Warrior mission yet, incase I want to moonshot farm, so that could make a difference.
I know you have to do with the "Doctors Orders" mission selected but do you have to finish the story mission "Wildlife Preservation" first? Will he appear if I still haven't completed Wildlife Preservation? I'm just farming him to get the skin that comes with killing him 15 times not for any weapons or whatever.
Its the same skin you get for completing Nothing Rhymes with Orange challenge... which is picking up orange items... which is 100% more easier than farming Jimmy Jenkins. --- GT: Nobody Worthy Current Games: Battlefield 3, Borderlands 2, Defiance, and Magic 2013.
