I would add to this debate that the reason why current non-permanent death systems are in place simply are too avoid players leaving their games for another.

Simply put players do not have this option when they cannot log out.

  Perhaps here one simply becomes paralyzed upon death, staring out their own blank empty eye until they are raised from the dead.  

Imagine spending weeks in that state waiting for someone to come help you because your entire party was wiped out.  One could go ma waiting for another group to save yours.
