Would it be possible to add a feature so that when a body part is not directly connected to the head, ie if an arm is dismembered you lose control of it. If the head itself is severed, then that player automatically loses. Could be a server option rather than a set thing. What you think?

Actually, the instantly-lose-when-you-lose-your-head -thing hasn't been done, but when-you-lose-your-arm-you-can't-control-it -thing has been done.

But I don't like this idea.

Yes, he's right. It's been suggested before.

This idea has been suggested, and made.
