World of Warcraft: Cataclysm will bring with it lots of additions and updates to game systems and class spells, abilities, and talents. Over the course of the next week or so, we'll be previewing some of these in the official forums, beginning with today's look at changes to dispel mechanics and rage. Beginning Wednesday, April 7, we'll start discussing what's in store for each of the 10 classes, including new spells, talent changes, and Mastery details. For the full schedule, check out the Cataclysm class preview thread.
