i say limit PKing to several areas, or maybe like in RS, the wilderniss. the further you go in the wilderniss, the better items and monsters. people should be in level range of about 5 to attack eachother.

that doesn\'t mean i don\'t like the gamble arena idea but then there should be several kinds of arena for every player what-he-wants and there shouldn\'t be any attack-level limit (so a lv 1 guy could attack a lv 20 guy)

and guildwars should be like (when accepted from both sides) that every member of a guild could attack any member of the guild they are in war with ANYWHERE. so people that want to PVP all the time could go in guilds. this would also connect PVP with interacting and teamwork.
