An idea I've had for a while regarding crafting was a solution to how on certain items, the normal quality versions are sold at a massive loss because everyone is trying to HQ and the HQ versions sell for obscene amounts because of how hard it is to accomplish.

My solution is to have secondary recipes for items with an HQ version where you add the normal quality version as an ingredient. This new recipe would have a much greater chance to HQ but failure would cause the loss of all ingredients used. Hopefully this would make crafting more viable for making money and make saving up for a HQ item much more feasible.
