Apparently no one really follows the update pattern or what Blizzard themselves have said. Updates for classes happen in cycles, much like the original class reviews in the pre-BC days. They are looking at a small amount of classes, comparing them to others, and then trying to change them appropriately. If they feel at a later time that one of these classes is still lacking, they will make more changes.Originally Posted by tortugapir8
Mages got A LOT of changes early on, they were one of the first major updates I remember reading about (but maybe thats bc I play mage). But anyway, I still see regular tweaking of the mage class, and we even just got a huge new spell (if it works right). Give them time, they can't publish changes for 10 classes every patch, or balance would be near impossible to reach.
