To say that the death knight community has been a little grumpy this past week is probably an understatement. Essentially, what happened is that we got a post from Ghostcrawler discussing some of our Mists of Pandaria beta issues, and in almost all cases, he wasn't quite on board with our complaints. This week, we'll hit some of the highlights of what Ghostcrawler said and what they mean for our class, as well as look at some of the changes we have seen coming from the beta.
It's not a disadvantage -- it's a feature
In the list of perennial death knight complaints, there are three that are probably pretty near the top and have been for a while. First, unholy pets and summons do not scale with mastery. Second, unholy has very little in the way of burst AoE. Finally, critical strike is incredibly undervalued for frost due to Killing Machine.
Ghostcrawler pretty much breezed through all three of these complaints with a classic "working as intended." That's not to say he didn't explain all three reasonings to some extent, but they all boiled down to the idea that the dev team is perfectly happy with the skills working this way, because they're all calculated differences that separate the death knight trees from each other.
