If there's a choice to enable or disable, why not?
That will look cool, and having a flowing trail of blood on comebacks will be pretty flowy

Let me clarify this. Do you suggest for the toris to leak out blood when damaged greatly, or for blood to stick on the limbs and joints? If it is the latter one, I agree to it. But if it's the former one, I disagree since it will not look good. It would look rather strange to me for blood to leak out on a limb like a faucet.
