Not surprisingly, the updates come rather close to the release of Age of Conan and are filled with content information and a nifty little Death Knight animation. The new WotLK gameplay features talk about some rather major changes to quest mechanics and, most importantly, raid mechanics. For the hardcore raider in you, the instances now carry a 10 and 25 man raid that are the exact same instances, but offer different ways to advance. Players taking on the 25 man content will get better rewards, but the shift is meant to allow more folks to absorb the new content.
If some extra power is needed, the new Death Knight class will be a welcome friend (oddly enough) in any raid or group with his all powerful skills. Unlocking this class of doom is an easy task. Simply have a level 55 character and the class is open to you. Then you create your Death Knight and start raising skeletons to do your bidding! The expansion is still in alpha testing, but make sure to check out some of these changes before you are left in the cold.
