Simple, the map is not an officialy a pvp map(as GM decode says). It would be hard for newbie players to farm (dragon scale, mini game token etc) because other players will kill them and if you can't force those players to go pvp room it is possibly they are afraid or they're just trolling or they don't want to fight you. You can @duel them in a place where no one can disturb. This is why i gave -1 to this suggestion.
