I really like this idea. But it sounds like crafters have to be present to attach materia to the equipment.

I like the idea of keeping crafters involved in the process, but if they could produce an item that anyone could use to attach the materia to the equipment, this would be much less cumbersome. It's never fun trying to hunt down a crafter when you need something done. And as a crafter, i much prefer being able to craft and sell while i'm away or offline.
