This is the simple thought:
After hammering out a lot of synths since the patch, I'm getting the impression that right now, Quality seems to be only good for three things:
1. Qualifying for an HQ(High Quality)/HY(High Yield) rank.
2. Getting better results from local leves.
3. Figuring out the recipe rank. (If you have questions you'll have to ask Pikko about this one...)
Especially about qualifying for an HQ/HY rank, there seems to be specific points you have to meet in order to get a +X quality item and different points to get a HY item result. However, the first tier for both appears to be really low. What I am curious about is, what is the lowest Quality any of you have gotten and STILL gotten a HQ/HY result for each of the tiers? So the lowest you've gotten the +1 equivalent and, if you have gotten those as well, the +2 and +3 equivalents for HQ and HY.
Lowest I've gotten for +1 was in the 30s for HQ and 100s for HY. Unfortunately it's been a while since I paid attention to it. I don't remember the lowest I've gotten a +2 at this point and I've never gotten a +3 yet.
