PKing doesn't bother me so much anymore.
Now due to my health advantage over most players I can kill them if they try to kill me.
Not many people try to kill me though, just the ocasional person.
Hopefully losing stats when you die will be removed soon then PKing won't be as much of a problem.
Also while on the subject of PKing you should be invunrable from being killed for like the first 5 minutes after you pick your class etc so the people that hang about where you start in sand don't kill you.
