In my humble opinion, its too hard to craft a good suit of metal armor, and too easy to craft a good psi headband. Metal armor builds have the least room to buff int; a lot of good tincan builds got neutered pretty hard by the update. I think that right now its too hard, but before the update it was too easy; something in between would be ideal. Psi headbands dont get an increase in crafting difficulty from enhancements, which is odd. Metal armor gets harder with each enhancement.
