It isn't the mats that are rare, but the fact that you need to be a specialist who can HQ a one star recipe. Even with all my classes at 60, I have a low chance of getting HQ on those items due to not bothering with Red Script grind and low total CP. Even if I WAS super equipped to make the items, I would only have the ability to make 2 of the unfinished products, and one finished product, due to being a bsm, ltw, wvr specialist. (hooray for fooling me into choosing specialties before telling me what I'd actually be making, you horrible monsters!)
Red scripts are bad (grind hundreds and thousands of items you don't want to be qualified to make what you want with a weekly cap to be mindful of) and specialties are bad (pick 3 classes to add mostly useless abilities to, some of which require you to burn blue scripts for a CHANCE at better RNG).
