world of warcraft -- In development

Patch 1.11

The next class up for a review of its talents is the mage, master of the arcane and the mystical energies of magic. Some of the aspects the class designers will be looking to improve include easing a mage's downtime between fights and opening some new, interesting talent builds through changes to all the mage's talent trees

New High Level Dungeon: Naxxramas

Floating above the Plaguelands, the necropolis known as Naxxramas serves as the seat of one of the Lich King's most powerful officers, the dreaded lich Kel'Thuzad. Horrors of the past and new terrors yet to be unleashed are gathering inside the necropolis as the Lich King's servants prepare their assault. Soon the Scourge will march again...

Coming in patch 1.11 is Naxxramas, a new 40-man raid dungeon that will present even the most experienced and powerful players with an epic challenge. Stay tuned for more announcements about this coming addition to the World of Warcraft!
