Recently hit 50 leatherworking.
got all my BiS HQ equips (though i haven't melded materia on them yet).

some questions:
can you not mass quick synthesis starred items? I can't quick synthesis hippogryph leather. do all star items require manual synthesizing?

when making profit off making stuff for the market boards and churning out HQ stuff, do you use HQ mats or NQ mats?

what's your rotation for 40 durability items, i pretty much have a 70/80 durability rotation figured out, but for short durability stuff like 40 that i want to try to HQ i'm not sure how to go about this.

suggestions on making a profit as a new leatherworker?
