Craft can be frustrating...sometimes, you have everything. The skills, the stats, the HQ mats...but RNG is just not with you and you end in a NQ craft.
What if crafters could improve their items with another craft ?
For example, you use 3 items in their NQ version and one Dark Matter cluster, and boom ! you can recraft your item for a new chance of HQ without having to gather all components again. (And if you still end with a NQ, you'll just redo it again...)
And of course, the difficulty and durability of the improvementt would always be the same as the craft itself.
Not harder, not easier, just another chance.
