I see your point, but supposed roleplayers, i.e. non-pk participants, will be affected. If I wanted to play non-pk, and I suddenly couldn\'t talk to any of my friends just because some people I\'ve never met, and I personally don\'t care about, want to fight, I\'d be quite unhappy. The fact is, pk and non-pk don\'t mix. One will always be affected negatively by the other, whether it is territories becoming useless, or balancing issues. PK and non-pk don\'t belong in the same game. Even if two instances of the world are created (different servers), the rules of one type of game will affect the other - spell use, etc.
If anyone ever played on a supposed PK server on EQ, you know exactly what I mean.
