The point of designated PK is to keep the game fun for everyone, if you want to PK, you can, just guild war or go to the arena, but if it was free for all PK, some people would exploit it, by killing those who are unprepared for conflict, those who don\'t want to fight, and helpless newbies who can do nothing but sit there, take a few hits, and die. As much fun as it might be for you to kill newbies by the handful, it is much less fun for them to have to die needlessly like that.
