I would like to see the Versatile Unarmed Strike feat added.
This is a feat from D&D (players Handbook 2) that allowed you to do Bludgeoning, piercing, or slashing damage with your Unarmed Strike. It requires that you have Improved Unarmed strike. This would be of great benefit to those Monks who prefer to fight Unarmed to emphasize the strength of the class (improved unarmed damage).
