The Guild Wars 2 blog has been updated with a lengthy post that lays out details about changes coming to the world versus world system. Players who enjoy WvW will be intrigued by the list of changes including advanced notifications of new builds, the Alt+F4 escape will be stripped and more.
Break Out Events are special WvW events that will happen when a team has lost control of all defensive structures, not counting supply camps. An NPC commander will appear in the team’s start area and an event will start that prompts players to gather around. Once enough players are in the commander’s presence he will summon his trusty dolyak to give all allies in the area full supply. He will then lead the charge to the nearby objective and give players protection and assist with building siege to assault the objective with. Those benefits, along with a defensive boon that he applies to all nearby allies, makes the attacking players a force to be reckoned with. Defenders will have their work cut out for them, as once the gate or wall piece is destroyed the commander will move to the tower lord inside and attack anyone in his path.
