The ability to 'throw' your weapon at an enemy. I know I'm going to hear some arguments that it would be a useless gimmick, and to some degree- you're right. But in the same degree- you could say that there are many useless gimmicks in Skyrim. But we welcome them.
It would be a great perk for Dual wielders, being that you would still atleast have one extra weapon in your hand. It also creates more diverse combat options when taking out enemies, other than your typical 'hack-and-slash' actions that take place.
So, lemme hear it- your thoughts?
Edit: By throwing weapons- I mean the ability to throw your axe, sword, mace, dagger, etc.
