Defense Sigil and Enchant
We added that sigil and enchant because death knights had difficulty reaching the defense "cap" in part because they don't have shields, ranged weapons or often tanking weapons. A DK who gears solely for survivability in this way is probably also going to have threat problems. Part of the reason we make tanks have to manage threat is so their gear choices aren't always as simple as "whatever gives me the best survivability." (Source)
Free respec in 3.0.8?
We normally only offer respecs to classes that have some significant changes in talent locations and costs. At this point there is no plan to allow for free respecs for death knights. (Source)
Howling Blast
Howling Blast was designed for AE dps, for which it was doing too much damage without a cooldown. We totally understand the concern about having a cooldown being awkward to work along with rune cooldowns, which is why we removed it. But that change made the spell too powerful, as we feared.
We will continue to iterate on the design and the ultimate goal is to remove the cooldown. There are some ways we can reign in the damage (such as a smaller AE cap or the damage falling off after the initial target) that will take some more time and testing to implement.
The DK is a new class, and while it is working well overall, you can expect to see some iteration on it compared to the classes that have been tested and upon which players have experimented for four years. (Source)
防御型魔印和附魔
我们添加了防御型魔印和附魔因为DK难以达到防御技能“合格线”部分是因为DK没有盾牌，远程武器以及大多数情况下没有坦克武器。惟生存能力是从来搭配装备的DK也可能会有仇恨问题。我们要让坦克保持仇恨的用意是让他们的装备选择不总是简单如“哪个给我最强的生存能力”。
3.0.8免费重置天赋？
我们一般只对天赋位置和花费有重大改变的职业提供免费重置。鉴于这点没有向DK提供免费服务的几话。
凛风冲击
吹风是设计用于ae的，因此它无cd的话dps会过高。我们完全理解一个有cd的技能拖着符文cd来使用会是多么麻烦的窘况，这就是我们之前移除cd的原因。但是正如我们担心的那样，去除cd让这个技能犟过头了。
我们会继续反复推敲设计，终极目标是移除cd。 有一些重新设计伤害的方案（比如减少aoe上限或者对最初目标外的目标伤害降低），还需要更多的时间和测试去完善。
DK是个全新的职业，总体来说现在设计的还不错，和那些已经测试和玩家玩了4年的职业相比会有一些反复。
