having perma death option is alright but it would lessen the game play length, Say you had finally bought that suit of black armor you had always wanted and you sell all your other armor to afford it. Then in the next battle you go into you hit by a stray arrow in the head and die instantly. If the main character could respawn like an Npc with all the original equipment that you had when you died then perma death could be a good idea. But i really dont perma death is needed falling unconsious is good enough.
