I would like to see an off hand implementation of different things. Right now it is mainly in the crafting system but I think it has a good deal of potential as a battle system because then you have the role actions, job actions, and off hand actions, which could vary for the type of item equipped. For example a ninja might have some ninja tools with three of four different sets of abilities depending on the type of too. a tank like dark knight might have a dirk or a paladin could choose between second sword, shield or club or a ranged attack weapon like a chain. the healers could throw enchanted rocks at party members and black mage could have a ceremonial knife to take party members life for invincibility. Machinist might have some AOE grenades and the Samuria could have some equipable incense with mystical qualities. I don't know, I'm just spit balling here I think it could be cool.
