Blizzard has also responded to the many players among the community that are concerned about class balance.
Let me ask you this, would you have preferred us to release each class with half as many spells and abilities just so we'd have less balance to focus upon? The efforts to balance this game will be a never ending process regardless of whether or not we introduce new mechanics. We'll never be fully satisfied and will always be looking to make improvements. Sure, new spells, abilities and talents will bring forth additional balancing concerns, but at the same time we're able to implement these new elements specifically with class balance in mind. Meaning, through allowing new mechanics to become available to all nine classes we can improve the current state of balance, while continuing to allow for further character development/evolution.
In the end, you'll be happy when you have some new buttons to push. ;)
