I'd be very surprised if they dont add new crafted gear (for DoW/DoM but also for crafters/gatherers) together with red scrips in 2 weeks. Maybe the new crafted gear is the class specific AF gear, so having a single strong set with melds for all classes will definitely help. But personally, i will wait 2 weeks and get the current BIS gear without melds for now. It seems like this is enough to craft all of the current stuff and i can still prepare and gather materia in case we gonna need melds for the new stuff, i just wont use them yet.
