DK pvp机理
设计DK职业的时候，我们想给予DK不同以往的pvp技能。特别的，我们不想给他们致死和大量的晕。
移除hot我们当时觉得是个不错的技能，它有着更好的泛用性，而且配合绞杀和思维冰冻，DK已经压制了非瞬发治疗。当时pvp治疗来说恢复德很强力，反hot也是个对抗他们的方法。
后来的赛季证明，坦克生存定位的技能在pvp中比想象的有用得多：冰韧，反魔盾和骨盾之类。死亡之握还是很强力，再配合减速，打断和不错的自我治疗能力。同时，天赋以及其他相关的变化也让恢复德不像以前那么霸道了。
结果就是我们不再觉得dk需要hot移除，而提高瘟疫打击的伤害到一个让玩家愿意用它的水平也会减小裸奔流的吸引力。

Death Knights PvP mechanics
When we designed the DK class, we wanted to give them some PvP utility that felt different. Specifically, we didn't want to give them Mortal Strike, and we didn't want to give them lots of stuns, because both of those have been done to death.
Removing hots we thought was an interesting mechanic. It is more situational than MS (since it affects different healers differently), and with Mind Freeze and Strangulate, we had given DKs a chance to cancel non-instant heals already. And yes, at the time, Resto druids were very dominant as PvP healers, so we didn't feel too bad about offering another way to counter them.
During the beta, many of the participants were worried that DKs weren't going to be functional in PvP. Even with Death Grip there were many dire predictions of kitability, which is partially why DKs ended up with so many diverse snare mechanics (though they have fewer now than they did in beta).
In the actual season though, it turned out the tanking-oriented survivability cooldowns ended up to be far more useful in PvP: Icebound Fortitude, Anti-Magic Shell, Bone Shield, etc. Of course Death Grip is still quite , and there are snares, interrupts, and even reasonable self-healing available. Simultaneously, many of the changes to both the Resto and Feral tree (Feral Charge for instance) as well as healing changes themselves made Resto duids less dominant than in previous seasons.
As a reult, we're just not sure DKs need hot removal, and consequently, that would allow us to justify bringing up the damage of Plague Strike to where players weren't so loathe to hit the button, which might also make "diseaseless rotations" less attractive.
