In preparation for Wrath of the Lich King, we will be performing an 8 hour Armory maintenance beginning on November 6, at 6AM PST. The extensive changes and feature additions in Wrath of the Lich King mean that we also have to update the Armory to reflect those changes. As part of the maintenance, all character data will be reset, and character profiles will be repopulated as players log into World of Warcraft. We thank you for your patience during the maintenance.
Depending on the amount of changes on Armory, WoW-Heroes might become unavailable for few hours to adjust to those changes. Thanks for your patience.
