What is a faction? Should I join one?
Alliances belong to one of two warring factions, the Kurzick or the Luxon, and being a member of an alliance allows participation in Alliance Battles. Victory in an Alliance Battle earns faction points, and members can spend their points individually or they can add them to the alliance bank, which will enable the alliance to acquire control of towns and outposts. The outcome of these battles influences the progress of the war between the two factions. The current battle lines, and indications of the control of cities and towns, are always visible on the world map. Guild membership in Guild Wars Factions is extremely appealing and interesting for both cooperative and PvP players. By joining an alliance and achieving success with Alliance Battles, your guild gains control of high-level towns. With that control, guild members acquire access to elite cooperative content. In Factions, the strongest guilds most likely will not be made up exclusively of PvP or cooperative players.
