I'm a bit behind on the times. Read that in U15 that the drop rate for Yellow Dopant was increased 5 fold.

My question is have the drop rates for Shroud ingred improved at all? Last time I've was doing Shroud runs I would run 5-8 times and MAYBE get one lrg devil scale and the quest reward ingredients selection was always ****.

Also is the Shroud the only legitimate place to farm lrg devil scales? Are there any other legitimate choices like Devil's Assault or some of the Amrath quests?
