Here\'s a thought I had only moments ago, so forgive me if it\'s not fully formed.
Why not have multiple spawn points in both realms? Each Life Realm spawn point would have a corresponding Death Realm spawn point. When you die, you spawn in DR nearest the portal which takes you to the LR spawn point nearest your point of death. If you really want to do so, you could make for a different portal, but such a journey should be at least as difficult as the equivalent journey between LR spawn points. In addition, each DR exit portal could have a small (for the sake of argument, let\'s say 5%) chance of sending you to a different LR spawn point, chosen at random, just to make life (and death) more interesting.
Any thoughts, comments or refutations? Discuss amongst yourselves... :]
