I was farming the space museum last night which had LMG's as targeted loot looking for a Pestilence. No Pestilence but did get an exotic chest piece, the ' Tardigrad ' from the final boss on the 4th run ,not what I was there for but pleased to have got it anyway.
RNG hates me I have never found a named item or a God rolled item in the open world, let alone any exotics. I've even farmed every difficulty from normal to legendary.
