I tested a new build using Bensch' stat numbers and got some interesting results. The new build is:

0/19/52 Obliterate

Rotation:
PS-IT-OB-BS-BB-DC-DC
GF-IT-OB-BS-BB-DC-DC
PS-IT-OB-BS-BB-DC-DC

You can simplify that to:
PS/GF-IT-OB-BS-BB-DC-DC

I just needed three lines so the sim would know to use GF every 30 sec

As you can see the builds are close in all respects. 1-18-52 scales better with ArP. Obliterate is still better than Scourge Strike with enough ArP.

I'm going to go out on a limb and guess GoFS=GoIT and FS=IT?

What did these sims look like without Ghoul Frenzy? Also can you link the 1-13-57 build.

Several questions regarding your specs and your results. The 0/19/52 spec you link has one point in KM. Why? It is pretty much useless since the only ability we use that takes advantage of it is IT. Why not pick up 1 point in subversion for 3% obliterate crit chance?

You say that 1/18/52 scales better with ArP, when in fact your DPS results show just the opposite.

Not just not better, the new GoIT makes Reaping much worse. Currently, the primary DPS benefit of Reaping comes from the extra cast time it gives, which loses most of its value without the additional RP from GoIT.

I have been running numbers for the "AE Mastery" 15-sec rotation 18/0/53 DW build I described briefly in my last post using the new 3.3 GoIT and the numbers look almost too good (or, in technical Blizzard terms, "feel lame"). For AE the advantages are obvious. You use more AE abilities; you are almost always near a Blood/Death rune to PE when adds spawn; you refresh Bone Shield without spending your BT.

Its AE rotation is also its single-target rotation and its single-target rotation can actually surpass conventional Unholy builds depending on a number of parameters (how long it gets to proc-roll, etc.), but there can be some add aggro issues with early tagging as mentioned in my last post. If you want to run this on live, you will want to change the glyph selection, of course.

15-sec rotation:

Initializing: BS>PS>IT>PE>DS>dc>DD
Repeating: BS>BB>BB>dc>PE>DS(>dc)>DD>dc

You can use Ghoul Frenzy every other rotation with a Death rune when not AEing, and Bone Shield every four rotations, also with a Death rune.

Edit: It is better to use the additional RP off the initializing sequence where the RP dump is in the repeating sequence (i.e., the (>dc)).

Yes please. Even just to be able to export gear-only stats would be helpful.

I'd like a mathematical reason why this would be. It makes no sense to me - as Necromir stated, 1 point in Subversion should easily out-dps 1 point in KM, considering that the only ability we have affected by KM is IT, and I can't see a chance at an IT crit increasing DPS by 40. Similarly, I don't see how GF would be such a huge DPS increase, since it's never been a DPS increase before, there's nothing in the spec that should make it sim higher, and there's nothing I've noticed in the patch notes that would explain it.

Any DK Engineers out there? I'm already sold on the utility and cool factor of Engineering, but had some questions about the pve dps aspect. What experiences have you had with Hyperspeed Accelerators? Who well do they stack with Gargolye? Thanks.

@Bensch78

Care to post these specs? I'd like to sim them for myself to see what I get.

KM is a PPM affect and makes for a guarenteed IT crit on a semi regular interval. It isn't an increased chance, its a set number of crits. That said here is a sampling from the sim combat log of IT crits:

IT crit for 4314
IT crit for 5430
IT crit for 5188

OB crit for 5845

PS crit for 2871

BS crit for 3120


As you can see IT crits are substantial damage.

I want to apologize. In looking back over my spec I'd left points in Outbreak during some initial testing that should not be there. My newest tests concur with Bensch that 0/19/52 w/ 4PT9 and the new IT Glyph is 8533 DPS

That said I'm not sure what Bensch is using for his stat numbers and the gear set on the first page is for two handed unholy, so I built a gear set for DW Unholy:

Slot	Alliance	Horde
Helm	[Frostforged Helm]	[Frostforged Helm]
Amulet	[The Executioner's Malice]	[The Executioner's Vice]
Pauldrons	[Thassarian's Shoulderplates of Triumph]	[Koltira's Shoulderplates of Triumph]

Then I re-ran my sims with realistic stats:

FC/FC 150ms

DPS 7688


Conclusions:
-Razorice offhand is simming higher than FC for both specs, most likely due to the scaling with the new glyph of IT
-0/19/52 is more affected by latency due to the extra GCD used for GF/IT where 1/13/57 uses a single SS
-The specs are very similar, Ghoul Frenzy being the major style difference. Neither clearly stands out.

EDIT: New version of the sim is out. 0/19/52 with FC/RI at 150 ms now sims at 7704 and 1/13/57 is up to 7691. There is a just an ~3% difference in the critical strike rate shown for blood plague and frost fever as well as a slightly higher rate of wandering plague. It seems the sim is considering 4PT9 and Wandering plague melee special abilities for purposes of annihilation, though I'm not sure if it should be.
