The issue of quick synth for 1 star and up has been noticed by the devs, no concrete response yet that I've seen yet.

The synths aren't an income source for me directly, but I have done thousands of them. I'm stockpiling the NQs of the 5 main 1-star mats in anticipation of level 50+ leves and GC turn-ins in the expansion, and spiritbonding DoL/DoH materia in the process. Last I checked the profit margin on NQ isn't worth the time it takes to craft them by itself, but that's been a while.
