As many of you know the next major content patch will include some very exciting things, such as Ulduar, a new epic raid dungeon, a wealth of new items, and much more. We thought players would especially enjoy reading just a few of the class changes we're currently planning. Please keep in mind, that this list is not at all comprehensive, and more importantly subject to change.

• Improved Water Elemental – this talent has been removed and replaced with a new talent that grants Replenishment (similar to Shadow priests).
  
• We are also working on a way to give frost mages Ice Lance “Shatter combos” in PvE.
  
• We are also working on more survivability for Fire spec in PvP.
  
• We are also working on making Spirit a more useful and interesting stat for all mages.

For details of other class changes upcoming, please check out the following thread in General:

Thanks for the feedback, folks. Yeah the announced mage changes were a bit slim, but of course they are just a preview of some of the changes being worked on. Thanks again for taking the time to write up your response.
