The Armory was a searchable database of information for World of Warcraft. Since the Armory pulled its data from the actual game servers, it was the most comprehensive database on the characters, arena teams, and guilds of World of Warcraft in existence.
While the Armory data got automatically updated, it was not a quite suitable replacement for traditional, non-"live" character databases. This is because it only saved a character's status after their last logout, so there was no way to display multiple sets of gear (for instance healing, PvP, or resistance sets) or the effects of different talent builds.
Every season, the Armory kept track of the top point-five percent of teams from a Battlegroup's arena teams. These teams were commemorated in the Arena Hall of Fame. Individual members that played more than twenty percent of a team's games were given special rewards, such as nether drakes and specialized titles.
We're in the process of deploying a new, open World of Warcraft Web API, which among other functions will provide a more fully-featured replacement for the existing WoWArmory website. Over the past few months we’ve been working with our partners and fansites to help them migrate away from using WoWArmory.com, and on August 2 we will decommission it, as well as the WoWArmory Facebook application.
When the Facebook application is turned off, users who installed it will no longer see it in their list of Facebook applications. They will also no longer have the ability to access Facebook pages that were associated with the application, and all news feed entries created by it will be removed.
Our hope is that through the new Web API, we can encourage a broad range of community-created features like the WoWArmory application, and are excited to see what else can be done by opening this information up to application and website developers.
