One question... sorry for being a noob question, I'm still leveling my DoH Classes (I have lvl 50 CRP, others tho are in the 20~30 range). But I've seen lots of people talking about using Basic Synthesis... But by looking at Careful Synthesis II, I'd say Basic Synthesis is pretty much retired for good once you get it?

Is there a reason to keep using Basic Synthesis once you get Careful Synthesis II?
