Yeah sure I understand that, but the basics are there whether or not them being collision based hit boxes.
The problem is at the end everyone will go for the head, 'cause that is an insta kill or at least it does the most damage even if protected good. So as long as we won't be able to "freely" move the head etc. to evade the blow it'll just get annoying.

Assume the end is always the goal. The path to this goal is the way you go. Now think about it, life is the way you go and death is were it ends. So what's wrong with this little devotion to the dead, when it's all humans goal to reach?
If the rest of humanity forces you to lie that doesn't make you less of a sinner.
