Open world PvP has the allure of PvP happening anytime, anywhere. Theoretically, players can vie for control of towns and regions, amassing in large armies to sweep the land of unclean filth. Or they can just zerg a spot and be zerged in return.
Instanced PvP is attractive for its tightly controlled setting. The teams are usually evenly matched in numbers, and clear objectives for winning are given.
