you never earned points for killing players lower than 10 lvls to you so thats actually just stupid players killing lowbies. Also I have never been a fan of ahkma cave maps are always pk free and where most new players are gonna go. New players wont know what ahkma cave is most of the time. And I have always advocated boost quests for those cancerous low lvls. There is more than enough grinding at the tail end of the game to make up for skipping some lvls to get to 90.
