It would be nice to have a permadeath switch for servers. It would default as off, but could be turned on for hardcore type servers. Permadeath is where your character is deleted if you die.
Since there is a recreate character feature, it would be easy to just make that feature kick in if a person dies on a server with permadeath on. The only issue would be if they were a clan leader. The game would have to move leadership to the next high rankling member. If its a one player clan, then it would disband the clan.
