Please ZoS, be creative and have jewel crafting create more than just rings and necklaces. Instead of having a 2h sword just count as two slots, let the jewel crafters make a gilded scabbard for it. Let them make quivers to be proud of, and intricate off handed charms and idols for staff users. The customization of the new traits in an off handed slot would let us fine tune our builds even farther than we currently can.
