I believe when Yoshida first talked about the crafting reforms, he discussed the changes to HQs. He had mentioned something along the lines of all HQ materials assuring an HQ. People were up in arms because it would essentially get rid of one of the few highlights of crafting if Quality/touch up didn't matter. I think you are right, and either they decided not to go with it, or maybe the translation or post wasn't entirely clear.

Maybe having all HQ materials will push up the HQ chance so far up that it would pretty much guarantee an HQ since they want HQ'ing to be less frustrating and luck-based, but with recent information it seems the quality/touch up parts of crafting will still exist.

It was from a really old post so I don't really want to go look for it lol ><;
