Okay, so I think what Caimie was able to do was reasonable. It required overmelding. It doesn't allow for automation (macro crafting), and can be replaced by non-overmelded facet gear for the same results. This is no different than crafting back in Heavenward when I got bored and quit.

The big difference now is the ease of getting scrips to unlock recipes. The ease of unlocking the gathering nodes, and the ease of getting materia.
