The biggest storms are often preceded by a sudden calm, as if the whole world stands still for a moment while the winds gather all their strength. This patch includes many important changes and improvements leading up to the release of World of Warcraft: The Burning Crusade, including the new PvP Honor and Arena systems. Prove your worth on the Battlegrounds and earn new, powerful PvP Honor rewards, or take the ultimate test of your team PvP skills in the new Arena System. Also, you can already learn the new class talents that will help you brave the many challenges awaiting you in Outland and beyond. There are many new, groundbreaking features to be found in this patch, but always remember -- this is nothing but the calm...before the storm.
