Enchanting seems to overshadow the other aspects of crafting by a large margin now. You mentioned a Spectral bow and a throwing hammer, are these full items we make or is the spectral/throwing bit just enchantment on an old item? 

Adding new layers of materials like Enchanted Wood or Obsidian Bone (for magic reflecting black bone armor!!) would be interesting ! Maybe stronger Leather/Robe/Rogue armor from griffin or yeti hides, that have more passive benifits as opposed to just higher armor, since right now you cant really make armor "better" than Ruby Platinum Plate without just being 100% immune to damage, but you "could" make armor with equal defense and innate HP regen combined.
