Crafters can use a "save" skill when luck trumps skills...

For me, Hasty Touch is just needed for 40 Dura 2 star Mats like Vanya Silk. Though even if I crafted a NQ Vanya Silk, there's is a rotation w/out Hasty Touch that always gives 100% HQ for 80 Dura 2 Star Items.

^ This mostly. With proper gear, cross-class skills, and technique there is some approach to 100% HQ every "finished" product in the game with 0% failure rate starting with full NQ mats.
