So when do you start wondering about being left or right handed? And provision of an ambidextrous trait? Just think where else you could apply this.... well okay its rather boring..
Wielding your offhand weapon should not be as useful as wielding in your usual manner... Then again come of think of it, does it really matter?
*makes note that he HAS had flags to indicate left or right handed, so that when the left or right hand/arm is cut off the appropriate object falls to the ground*
