So i got every crafting class to 16

You technically can, unless that 10% rears its ugly head (it only boosts reclaim chance to 90%). And the 50 cp cost is still pretty hefty, esp when it comes to HQing star crafting. Though I'd imagine CP is not as important when it comes to crafting 3* furniture or glamour items (like the primal demimaterias).

CP is actually more important for 3* crafting, because their difficulty necessitates using things like Piece by Piece and the elemental brands, which require CP. Reclaim is worthless in 3* crafting and you will lose far more money from a Reclaim fail than just making it NQ.
