I hope the mass quantities thing is definitely true for lower level synths at least. As a Lv50 weaver, for some reason I find myself very low on cotton yarn and cloth. I have 3 stacks of bolls, yet I can bring myself to make any yarn only when I absolutely need to. O would love to turn 2 of my stacks of bolls into yarn, but making 3 yarn at a time even with hasty hand is beyond tedious. So I don't bother. I'd love some way to have low level recipes(maybe -10/-15 of your level?) be just 1 click mass produce with no HQs. If you want the craft to take a while, whatever, I'll hit craft and go AFK.

But expecting me to sit there for hours making cotton yarn at lv50 is not fun, is not a test of any skill, is not hard, it is simply frustrating and tedious. Adds nothing to the experience.
