Simple idea, The ability to DUAL WEILD UNPREPARED swords or daggers.
Just to give a cool look to the game. Possible to put the sheild on the back or maybe not have the ability to have a shield while you are dual weilding.
The way I figure it, you could already right click menu certain items like hat and robe so why not maybe change the shield slot to SWORD or SHIELD. That would be so awesome!
