BoB heads/skins

Played through DLC3 with all 4 chatacters. Farmed the Ruiner at least 50 times over the last couple days. Made mad $, endless echo skins and room decs, choked on legendaies. Not a single head or skin for any class.

Anyone have better farming suggestions? Loaded Dice makes no dif. Would trade what I can, only on M6 atm tho.
