The arrows topic made me think of this, does the skinning code take into account what kind of damage was taken (Or at least the damage that dealt the killing blow) as to what you can skin? If not, I think there should, certain types of weapons will make some parts of skinning easier... some weapons will make some parts of skinning harder.
I'm just wondering if this ever got in, because it seems like another one of those "Think about things logically, and you'll do better" like sandcloth, and regaining stamina faster indoors, etc.
