I was playing a GTA: SA server, and I saw a nice system that prevented you from dying too quickly and making it unrp -
Once your health depleted, you would, instead of dying, would play the death animation and have to wait for EMS.
Now, I think to make this add-on compatible with most roleplay situations, you would have to leave out keywords like EMS, because then there might not be any EMS in a wasteland RP, so your best bet would be waiting for a helping hand with a medkit or such. Of course, there would be a command to just end your life instead of waiting to bleed out. I think this should work in conjunction with RP names, so that you can't stay as the same character once you die.
