Right now, you can craft from 1-100% quality with HQ crafted gear and only tier 4 or below materia melds used. Obviously this gear setup isn't future-proof but it shows that there isn't even a lot of effort needed prior to crafting in order to even get the numbers.

I think I've suggested it before, perhaps in this thread or in another, but they should give each master recipe a different handicap, such as "can't use cross class skills from LTW" or "can't use delicate synthesis". Leave leveling recipes as they are, give endgame crafters something to think about, a little more intimacy with their skillsets rather than just pushing a macro button. Ultimately people will set up macro's for each variation of handicap eventually, but we at least get a period of time where some idea of difficulty or brainpower is required.
