For people who would prefer the pacifist approach, can there be an option for players to be immune to combat against other players?
(This would go both ways, so they couldn't attack players OR be attacked by players). Turning this on and off would have to incur some kind of penalty, to stop abuse (Or can only be toggled once per 24 hour session).
I think this would be better for the people who do not want to participate in PvP activities.
