open world pvp

PVP that takes place in an Open World. Many instances of PVP take place inside instances, zones created for the PVP in which set numbers of players fight in their own personal map until a victory condition is set and that copy of the map goes away. By contrast the Open World is a non-unique setting that you and other players can freely move around, so Open World PvP contains a lot of unpredictability and often starts with randomly encountering hostile players.
