PoSG

Notes of interest to Unholy PvE DPS:
•Endless Winter: No longer causes Frost Fever to be applied by Chains of Ice, but instead grants 2/4% strength.
•Icy Talons: The personal haste benefit provided by this talent is no longer exclusive with other sources of melee haste. This will allow death knights to always swing 4/6/12/16/20% faster when Frost Fever is applied. Windfury Totem and the party/raid component of Improved Icy Talons still do not stack.
•Scourge Strike: Now deals 70% weapon damage, plus 12% of physical damage done as shadow damage for each of the death knight's diseases on the target. The net result should be larger strikes with no diseases present, while maximum damage with all diseases applied to the target should stay the same.

At first glance, the SS change may seem like the most important of them all. With the physical strike going from 50% to 70% of weapon damage and the magical strike being reduced from 75% to 36% of the physical damage, surely that means something, right? No, not really. Blizzard actually managed to change our core ability to increase PvP potency without really any adverse effect to our PvE performance. Who knew such a thing could be managed! It does actually increase the damage of SS ever so slightly (about ~3%), but it's hardly worth noting, and doesn't actually change our spec, stat weights, or gearing.

The changes to the Frost tree, on the other hand, do mix up our spec, weights, and gearing. The reason why is due to the increased attractiveness of a Frost sub-spec as opposed to a Blood sub-spec.

But after it was buffed so much, how can passing up Subversion possibly result in a dps increase?
How can taking BI, when less of SS's damage will be affected, possibly be worth it?
By dropping Reaping.

It breaks down as follows:
Sub-Frost + Reapingless > Sub-Blood + Reaping > Sub-Blood + Reapingless > Sub-Frost + Reaping

Frost Reapingless pulls ahead of Blood Reaping by about 50 dps. It's certainly possible that the latter will pull ahead in BiS, but it does have a decent gap to cover, especially when you consider the majority of tests were already using a 277 weapon, and the weapon was the largest factor in whether or not one took Reaping.

At any rate, the exact build will be 0/17/54. The glyphs are intentional: GoBS pulls ahead of GoDD by about 5 dps. GoDD will still be superior in most cases, simply due to RP via Revitalize/AMS, but GoBS is an option worth noting.

Theorycrafting is still ongoing, and stat weights/BiS lists will be posted once things are more certain.

As always, this entire section is subject to change, as it is the PTR.

Rogues will have nothing on me!
