Being taken by surprise
As we have done in previous expansions, we plan to release a patch that updates the game systems shortly before the full expansion content goes live so you will still be experiencing Phoenix Dynasty Gold with the new stat systems for at least a short period of time. All classes will be changing a lot in Cataclysm and we will announce all of the changes in advance to try and prevent players from being taken by surprise. In the mean time, please make your item selections with both current and future content in mind.
