I have not done the math or intend to, but that gear with supra and the new off -hands melded should make you a 4* capable crafter.
totally agree with you that skill and experience will keep people out of the 3*-4* hq market, but people like glam and you don't need hq for that which is why sometimes i'll put up some nq items for the hell if it. especially the bard kirimu coat.
that being said those mastercraft 2 books will definitely seem impossible to non experienced crafters not to mention the cost for them if you fail too many times which lets face facts is easy as hell to do even with reclaim.
in truth though im happy about that as we don't need to much competition do we....p
