For these new-old bosses the sequence seems to be:
 * drops 001-050 (milestone 15) get you to craft the boss non-plus. level that up to 35 to unlock crafting the boss+.
 * drops 051-100 (milestone 43) get you to craft the boss+ (after the previous step). level that up (someone on KnD forums said only to 10; not sure if that's true) to unlock crafting the boss++
 * drops 101-150 (I think you already get to that at milestone 60 unless they changed things) get you to craft the boss++ (after the previous steps).
 * drops 151-200 (at milestone 62) get you to craft another boss++

So newer players now get worse armors from boss non-plus and boss+ than about 2 months ago and players who can consistenly get to milestone 60-62 probably see it as not worth crafting, since the boss++ is weak compared to their lineup and getting 3-4 non-plus for fusion likely wouldn't have any possible fusion result at the moment that aren't weaker than their lineup... *facepalms at Gree*
