You have to change the DefaultLootRules. I have one that I have edited that I would be happy to email you if u like. I have found that by not looting anything but gold itself has made my gph go up so I no longer loot. I gained about 40k gph with this change. True u do loose out on some possible yellows but lets be honest most of the loot is garbage anyways and not really worth your time. I just bot and collect gold, keep it simple.
