Since the last time we talked, we have seen a couple of new updates to the Mists of Pandaria beta. There haven't been many earth-shattering changes for death knights, but some of the changes have been significant enough that it's worth talking about both what they mean for the class and what they may imply about future updates.
It's difficult to say where Blizzard is going with our class in Mists, if only because they haven't said much. They've started talking on the beta forums, but they haven't directed anything at the death knight class yet. This isn't completely surprising. Our class is not in a horrible place right now, and the beta's young. Chances are we'll get our turn eventually.
That said, having developer feedback is useful for figuring out how to mold your own feedback. Knowing what a developer intends with a certain change can help us test that change with a better understanding of how it fits in to a larger vision. In absence of that, however, we can still look at the implications of these changes to see what we come up with.
