I did the sims with 3-13-55 OB (7181 dps) and not 0-17-54 OB (7210 dps). The difference is bigger then to 17-0-54. (7247 dps - 0,5%(Subversion) = 7211 dps).
And i don´t really buy your argument about the AoE loss. WP has more chances to proc. Don´t forget that you have 5% more crit. Only two more procs in 20 seconds (which is possible with 5% more crit) would close your AoE-gap.
Anyway, i just wanted to point out, that you could change specs right now, if you want to get back to SS as soon as possible. My own gear has far more haste, for me changing right now is pure win.
Let´s start with diseases, pestilence and then drop D&D.
Repeat this Rotation.
How would you change that rotation with D&D on 15 Seconds-CD? You would destroy the entire rotation. You could not target D&D before the necessary runes come off CD. So the point about the delay does not really fit.
You won´t win anything really with the shorter CD on D&D. With 15 Second CD on D&D you could D&D in second 23 instead of 24,5. Winning only 1,5 seconds, but delaying and destroying your further rotation.
The Epidemic-less results are interesting, but the problem is AoE. On a single target, it's essentially a matter of PS + IT verse SS, and similar to 2x BS, although the SS wins out, it isn't by much, and the extra talent points/RP apparently push the first option over.
Disregarding AoE, if PS+IT is similar enough to SS, would a form of the old Frost IT Machine Gun spec work if we dropped SS all together and picked up the IT Glyph and Death Rune Mastery to proc more RP for DC/UB?
Haste becoming valuable plays no role on weapon speed (well, no important one).
IUP is not a dps boost. Using UP automatically brings your GCD to one, which kills half the (presumed) reason haste is so relatiavely valuable now. What more is the fact that although 17/0/54 uses more GCDs than can fit in Blood normally, it doesn't use enough for Unholy - in Unholy Presence, you would have empty ones, which kinda kills it. I tried various sims with UP/IUP and couldn't get it to be a boost, and there's really no reason it should.
As I said, the difference is very slight either way with the current specs. The reason I used 0/17/54 in my comparison is simply because it was the first option from the drop down menu and because at the gear level of the 2H ulduar set, it would indeed be superior, and if the idea was to see if switching now was a dps gain, that's the comparison one would want to make. As I said, there's nothing wrong with switching specs now, and it is indeed quite viable, but it's not a dps boost (well, with your numbers, I guess it's a boost of 1, but a margin that small is just going to be covered up by RNG one way or the other).
The WP gain wouldn't be enough to undo the already discussed Blood Boil loss. Not quite. Does narrow the gap though.
You can DnD in your chart at 19 seconds. And then at 34 (you can simply apply/spread diseases afterwards, and they won't have dropped), etc, etc. So on and so forth. You can certainly make use of that extra 5 seconds off, so I am not quite understanding what you are getting at. You can DnD every 15 seconds without running in to the problem of it coninciding with diseases needing to be applied/spread - because you have a 5 seconds window in which to apply diseases after when you normally would have (since diseases have the 15s duration yet are normally applied every 10 seconds). Hence if you used DnD at 34 because you had previously used it at 19, you would then PS/IT/Pest on 35.5/37/38.5 (your last pest was at 23 seconds, meaning that diseases fall off at 38. So long as you have even the slightest bit of haste on your gear, plus the haste you get from raid buffs, it will make that cut off. Even if it were not to, you could just delay using that pest at 23 until 24, as it would have made no actual dps difference since your DnD doesn't come off cooldown until 34 anyways).
So, yeah, Morbidity = you can use DnD five seconds sooner then you otherwise would, giving you a 33% increase in DnD damage over an infinite period of time (10/15 seconds over 10 / 20 seconds = 1.33). In reality, it's obviously not that large of a gain since fights are not of infinite length, but to say that third point is meaningless is quite incorrect. You do get something out of it: exactly what it says, the ability to use DnD five seconds more often (something which is completely doable without losing dps, so long as you actively think about your rotation).
With Epidemic, yes, making full use of that last point of DnD becomes difficulty because you don't you have little leeway as to win you refresh your diseases normally and when you would if it gets pushed off. Without Epidemic, you don't have that problem since you have a 5 seconds - 3 gcds, the perfect number - window each and every time.
I tried using a PS + IT build, but couldn't quite get it to work. The reason why being disease clipping (which will be a bigger loss than ever with 4p t9), Sigil of Virulence (you would lose its proc in such a spec), and gcd limitations (you can switch to UP, yes, but then that entails its own tradeoffs). I did not try PS + IT with DRM, but that's pretty much going into the old IT x6 rotations of Frost, practically. Although it may be viable, it would almost certainly be better to do it DWing, since the only abilities being affected by weapon damage would be BS/PS.
If this is meant to be an AOE rotation then you dont really need to repeat PS+IT, simply switch target and use Pestilence effectively saving yourself U+F runes
1. Because you will lose the diseases on the target you switched to. The duration is only 15 seconds without epidemic. Until you switch again you have lost the diseases on your last target.
2. What do you want to do else?? SS?? would be less dmg... You don´t need to switch.
Hence if you used DnD at 34 because you had previously used it at 19, you would then PS/IT/Pest on 35.5/37/38.5 (your last pest was at 23 seconds, meaning that diseases fall off at 38. So long as you have even the slightest bit of haste on your gear, plus the haste you get from raid buffs, it will make that cut off. Even if it were not to, you could just delay using that pest at 23 until 24, as it would have made no actual dps difference since your DnD doesn't come off cooldown until 34 anyways).
That´s wrong sorry. If you D&D at second 19.5, this runes used will be available at second 27.5. Doing nothing from 23 on... wait 4.5 seconds for the runes to come back (2-second-window). Then let´s do a SS and BB. This runes will be again available at 37.5... to start your diseases again (Just did a D&D at 34.5). 37.5/39/40.5. You lose disease uptime on every target for 2.5 seconds. Second 38 to 40.5. If you are the only UH-DK not really an Option.
If you want to use D&D in 15 second-intervalls without Epidemic, you are not really able to use BB.
I just wanted to show a 20 seconds rotation you could repeat. 20 seconds D&D fits very nice in there.
Another thing to keep in mind is the fact that if GCD availability is the primary benefit of haste for Unholy in 3.2.2, it'd be good to determine the exact point where it no longer provides needed GCDs and what it's EP would be after that point.
Basically we have 22.5 seconds currently worth of spells in the Reaping-less rotation, so the question is, considering not all of the abilities we'll be using are spells, how much haste would it take to chop 2 GCDs off the rotation?
8 of those GCDs are melee attacks, and 7 are spells.
So we need to chop probably about 2 GCDs off to make room for latency/user reaction speed.
So we'd want, what, about 29-30% haste then, optimally, no more?
Edit:Actually, I'm only coming up with 12-13 GCDs per rotation, not 15, what am I missing?
IT PS BS BS SS DC (1 second gap) SS BS BS SS DC DC is 12 GCDs+1 second, 13 GCDs when RP overflow allows a second DC during the first runeset in the 1 second gap. That's 19.5 seconds, just barely within the 20 sec rotation.
Losing BBs is an Epidemic issue, not a Morbidity issue.
In the case you're talking about, you can instead spread diseases at 34.5 and DnD at 37.5 (which is 18 seconds from your previous one. Still a gain over 20 seconds. If you wanted to keep going, it would essentially fall like that - 15 seconds between DnD and DnD, then 18 seconds, then 15 seconds, etc). Although perhaps not the full gain, it is most certainly a gain. It just doesn't make a for a "clean" rotation. Priority system ftw?
Also, beside the point, but you should SS before BBing. SoV proccing and all.
I was trying to figure that out earlier. With 15 GCDs, you're at 22.5 seconds. You could bring that down to as little as 19 seconds (7 spell gcds, minus 0.5s each). Optimally, you would bring it down to 20 seconds.
However, if you bring it down to 19, you have an extra second (which is an entire spell gcd at that point), which would allow you the perfect place for Ams/Revitalize -> DC dropping. So, yeah, going all the way to the spell gcd cap should be fine. I doubt you'll get all the way there in BiS, but it does mean you shouldn't worry about getting too much of the stat. There just isn't that much of it on good gear and, unlike hit and the like, it isn't worth going out of your way to cap or anything like that.
You have the rotation wrong, which is part of where you are missing GCDs. Remember, no epidemic and no reaping. Thus:
PS IT SS BS BS DC Horn DC // PS IT SS BS BS DC DC = 15 GCDs and not a single RP remaining.
So, I've read through the whole thread, and I didn't see a reason why we shouldn't pick up black ice. Is it because 4pc t9 makes the crit from blood better? If so, then what if you don't have 4pc t9 yet?
Oh, duh. Butchery. Yeah, that means one HoW every 5 'rotations' (100 seconds) as you said. It would be a dps loss beyond that (or with enough RP coming from AMS/Revitalize to make that one per 100 irrelevant), as you will always have something else you could do which actually caused damage. Always can use it on movement, of course.
So, I've read through the whole thread, and I didn't see a reason why we shouldn't pick up black ice.
Because it does less damage than the alternative? =p. That's really all there is to it. You spend 10 points to get 15% IT damage, 10% Frost damage, and 10% shadow damage. Alternatively you can spend those points in Blood and get 9% SS crit, 9% BS crit, 2 RP/5 seconds, 4% weapon damage, and however much AP 3 points of Bladed Armor gives. The latter simply wins out. Scourge Strike and DC aren't as large a portion of dps as they were in 3.1 (especially when you factor in no reaping and no epidemic rotations), and thus Black Ice doesn't scale as well.
Is it because 4pc t9 makes the crit from blood better? If so, then what if you don't have 4pc t9 yet?
Even without 4p t9, X/0/Y is still better than 0/X/Y.
Might be better suited for the BiS thread, but I'm showing [Comet's Trail] trumping [Darkmoon Card: Greatness]. Are others getting this result with their sims as well?
edit- This is with the no-reaping, no-epidemic build, of course.
Well, doing things the old fashioned way:
Greatness = 90 STR passive + 300 STR proc x 33% uptime
Greatness = 90 (3.05) + 100 (3.05)
Greatness = 579.5 AP
Doesn't quite win out, although due to the fact that the gap is so incredibly small, depending on how Zerack's calculates the uptimes, the latter could be slightly on top. But then you have to remember is that if all of that haste (which is quite a chunk) plus your haste on gear plus haste from a ret paladin/moonkin/etc is enough to put your gcd where it needs to be, with that point depending on your latency and such although Bensch showed the estimate abopve, it will begin to lose value.
