I got a whopping 125 DH for all my hours of grinding. That is the best rng have given me so far. To be honest as long as I can continue to work on that weapon in the next area im not that bothered, mine is for glamour. But for people who want to actually use these weapons its awful.
I think they should come with a very basic and useable set of substats and that the light grind should be there to roll to make those better, as if its more of an optional step.
