so since patch you have a much easier option at hand.. craft for the new gear from the trade ins. with those and supra you should be 4* capable, but def 3* which will then let you craft all the bis gear anyways.
all you have to do is meld one class high enough to make the turn in item. which is a simple thing to do.
good thing about those pieces is there all cross class and no melds needed, def easiest way to catch up to all the other 4* crafters.
even if I hate SE for making it so damn easy
