Or, add a fun thing to your system that keeps people from PKing newbs with no weapons...A sort of 'newb invulnerability', if you will...Except make sure that newbs can't hurt other people either, until they achive whatever standard it is that makes them vulnerable...And if you're really clever ( like me =D ) you can make it so newbs can still get hurt by npcs, baddies, etc..So they can get the hang of fighting before being faced with the massive hordes that are the PKers.
