Class Balancing in patch 2.4?

Some changes, but probably not huge ones

Blizzard answered some questions today about class balance and patch 2.4. They also let slip that there may be an additional patch before the release of Wrath of the Lich King.

Q u o t e:
Will there be some class balancing in 2.4 beyond what has already been stated. I keep hearing that there is supposed to be some pretty significant balances, as there should be. Can we get at least a teaser?

I'm going to be a bit cautious in what I say in this regard. Will there be some changes to classes? Yes, there will be some. We're not rushing into a bunch of class changes for this patch at this point. Consider the patch to be a bit more progressive in nature. As we go along, the developers are going to be keeping a close eye on the results of any changes and additions and then making changes as they feel they are necessary. How many changes occur are going to be based on testing over time. This is why it's important for players to get in and test it as much as possible.

We want to make sure that the changes we are making are viable and practical for continued balance of the classes and don't want to put in too many changes at once and essentially skew the results too much one way or another.

Keep in mind, we do have Wrath of the Lich King coming up, in time, that will extend the level cap to 80 which is going to mean more additions and changes to classes. We will also patch between the Sunwell Isle patch and the release of the expansion as we feel it's necessary.
