I suggest this because it would be fun to have in this game and I can imagine the PVE, PVP and RP servers playing out with perma death going on, it would be FUN! Everyone on it would have to struggle just to survive! All KINDS of drama would unfold if this feature was added, it would be amusing, yes I too play perma death; hence why I suggest this. 
Edit: Factions/ Empires would rise and fall, kinda like IRL, immersive as hell! it would be fun!
