is what you're looking for.
The extra Ghoul Frenzy is there in case you want to use that again before BT comes off cooldown. BT has a 1 minute cooldown, GF has a 20 sec cooldown.

Due to the way castsequence and reset is implemented in the game, I would use a shorter reset in that macro, probably 35s or so. Every time you hit the macro, the reset timer is, well, reset.

I never see the [Glyph of Blood Strike] mentioned here as a valuable option for Unholy-DPS. Why? With Desecration we get a snare effect on the target and we throw a lot of blood strikes on it. Is the 20% dmg boost to Bloodstrike, compared to 15% Death Coil, 20% Death and Decay or 10 secs more Unholy Blight that bad?

Check the proportion of blood strike damage to overall and do the math. You blood strike a maximum of two times every 20 seconds; often less when AEing. More importantly bosses can't be snared, so it's a PvP glyph.

pretty simple
your RP dump is DC and UB (which you should ideally have on at all times) thus you'll be using these all the time
BS gets used twice per rotation (about every 30 secs or so) and the damage it does is not very substantial even when it crits. I'm pretty sure the math was already discussed in this thread already but even without it you can see based on the rate of BS use that you are not getting full benefit out of it.

AFAIK the snare effect works for mages on bosses too, why not for this glyph?

edit: Ok, ignore this. Thanks everyone. I think, this information with blood strike should be included in the main post to avoid another occurance of this discussion. ;-)

back to Ghoul Frenzy, not sure what i was smoking that i was left with the impression that it costs 1 Blood Rune (hence all the rambling) but I stand corrected.

However that makes it even less desirable in my eyes. the unholy rotation is already starved for runes as it is, isnt this point better spent in Necrosis or even Icy Talons (considering 0/10/61)

Also now i'm rather lost as to where GF fits into the rotation, i understand it's after SS but which SS?

If you are going to use GF in a rotation it's best to use it with Blood Tap rather than trying to work it into your rotation proper. The best time to use it, in my opinion, is when you've used all your Runes but the Blood ones, if you Blood Strike, Blood Tap, Ghoul Frenzy and then Blood Strike again you'll end up with Ghoul Frenzy up and both of your Blood Runes as Death Runes for long enough to let you get a Scourge Strike off next time they refresh.

-Edit-

My apologies, question was answered. Thanks Amero!

I don't see the problem. Every Unholy has Reaping skilled. As soon as you can spread your diseases on any secondary target you replace the next BS with a PE.
In the case that Blood runes won't be coming up because of Death Runes you still go PE, BS with the Blood/Death Runes.

I noticed that this has to do with Blood Tap. It seems its bugged in a way that makes it's timer that turns blood taped death rune into normal rune to work no matter what. For example, If you blood tap a blood rune, than use ghoul frenzy, after 10 seconds you use blood strike off that blood rune which turns it into death rune, and after another 10 seconds when it is about to refresh, it turns blood rune again by itself. This thing always happens after I use blood tap so its gotta be something with the blood tap timer.

Has anyone droped the SS glyph for UB or IT glyph?

With moving from 4t7 to 4t8 I don't see any big reason for spamming SS.
SS used to give 30RP while PS+IT gave 25RP (without IT glyph). At the time SS was more damage than PS+IT AND it generated more RP. In Ulduar things changed.

These numbers are taken from my Ignis log, wearing mostly naxx gear with 4t7, World of Logs.

Average values:
SS - 6913
PS - 2745
IT - 1640
DC - 4481 (with 2/3 Morbidity)
FF tick - 951
BP tick - 982

For Scourge Strike: 6913 damage + 25RP (with 4t7), will be 20RP with 4t8

Comparing to PS+IT:
ps+it = 4385 damage + two disease ticks (since SS glyph will clip them)
ps+it = 4385+951+982=6314 damage
This will also generate 25RP, that's 5RP more, or 1/8 of DC=560 damage

Looks like SS and PS+IT are really similar in damage output. But PS+IT combination also gets a new glyph and looks like a clear winner over an aditional SS.
Rotation would become similar to frost OB heavy: PS-IT-BS-BS-SS, SS-SS-SS
UB glyph gives one free DC every minute, while IT glyph would give 30RP every minute, or 3/4*DC.

I know that SS will hit harder with 4t8, but with 100+ strength from new gear so will disease ticks and DC damage go up. Can anyone provide any numbers with full tier bonus and more ulduar gear?

Going one step further on this, wouldn't it be possible to simply put:

#show Ghoul Frenzy
/cast Ghoul Frenzy
/cancelaura Blood Tap

as your Ghoul Frenzy button? If you have Blood Tap, it'll use what is (presumably) your only available Death Rune and then switch it back to a Blood Rune. If you don't have Blood Tap up, it'll just cast Ghoul Frenzy per normal. If this is functional, would it not also change the order of preferred Ghoul Frenzy-ing from BS --> BT/GF --> BS to BT/GF --> (cancel aura) --> BS --> BS? This way you would get the Frenzy, the 2 Blood Strikes, and a Scourge Strike the next time around the rotation.

I too have struggled on how to effectively use Ghoul Frenzy without feeling like I'm either losing DPS (using a set of Death Runes for GF + IT) or making my rotation horribly awkward via the Death Rune / Blood Tap interaction, so this would be quite helpful.

Can you clarify what you mean by SS glyph will clip diseases?
are you saying that refreshing the diseases also restarts the tick timer? (has this been tested)
if that is indeed the case than you're loosing a lot more than 2 ticks depending on Glyph proc rate, and that seems unreasonable

Yes it has been tested. Refreshing diseases through the Scourge Strike glyph has been proven to reset the ticks of the diseases.

As for Zagor, it wasn't stated which spec you're using and armory isn't currently functional but I'd assume you're using a spec other than the 0/10/61 spec. This is an example of the 0/10/61. Ignore the DPS and pull out the separate numbers from there for your calculations.

EDIT: Rewritten to be more encompassing.

Has anyone given consideration to a build along the lines of 10-10-51. I have used this build with [Sigil of the Vengeful Heart] and 4pc t8.5 and I get pretty good results. Death coils crit for ~10k as do scourge strikes. The aoe of the build is less but still not too bad overall. I dont get unholy blight because its just easier to DC and the build is lean on points in the unholy tree.

The thing is BA effects all of your damage whereas 2h spec only effects auto attacks and SS. Considering the armor gain from 15% armor in the frost tree I had gone that route. Thats not to say you arent correct, thats just how I was running it.

I did some math and its very basic but the 180 AP difference (for me) was about a 3% white damage difference on the character sheet. When you include the damage gain on DC and diseases I think the difference is pretty minimal either way.

As a sidenote around 45% of my damage is with my weapon (this is just for me mind you) and another 55% is all influenced by attack power (including ghoul at 10% of damage done).

Also UB gets closer to DC with talent glyph and sigil especially in this spec. although I havent specced it for awhile if I recall correctly UB cant crit and DC can. My DC's crit for 9-10k avg about 5700, UB is very close to that in a per cast damage. I just cant find a talent point to drop to pick up UB considering per cast its only maybe a 300 dmg on avg gain, on one target.

UB has consistently been shown to be better damage per RP than Deathcoil. This was true even back when UB cost 60 RP. Earlier in this thread it was shown that even with the Glyph, Sigil, and 2p t8 UB is still a far better investment of RP. There aren't even any fights (talking about Hard Modes) that I can think of where you're away from a boss enough to make DC better. Randomly on Hodir, maybe, but generally snow patches land on melee. P2 Yogg is pretty bad for UB, but you should be able to get a full duration on the brain, and UB is amazing in P3. Vezax, Thorim, and XT all have pretty much 100% time on the boss. In P3 Mimiron UB will hit all 3 body parts, again making it amazing.

Using DC because "it's just easier" is dumb. That's like saying you don't use diseases because it's just easier to mash SS. This thread isn't about what's easy, it's about what's best, and UB has consistently been shown to be better than DC.

Additionally, hybrid builds like 7/10/59 and 10/10/51 have been greatly discussed here as well, and also been shown to be inferior to simply picking a Blood or Frost subspec. The talents you give up in Unholy are simply too good. If you want to play some kind of Hybrid spec like you listed, go check out the DW thread, as I think that's similar to what they use.

As I stated in my last post however, my DC's avg 5700 and UB assuming 20 ticks of 300 with 100% uptime is 300 more damage 1 tick off makes it equal. I havent read the entire thread yet but I have not seen any discussion as of yet about a build like the one I used.

True, but it has also been suggested that once you break 4p t7 you get far more of a damage boost by switching out Dark Death for the UB Glyph.

Perhaps your math is a bit off. A glyphed UB will tick 30 times in a 100% situation. SOLO, non-raid nor even group setting, my UB ticks for 227, with simply HoW and a 0/10/61 spec.

227 x 30 = 6810

Compared to your 5700, you would need to miss at least 5 ticks to make it inferior. However, in a raid it can tick for over 300. Not going to bother with the math on that. My point is proven. Also, the reason no one has spoken of your build is probably because the math has already been done and it was found inferior. Look for it on page 16 and beyond.

EDIT: Added exact page for 10/10/51.

This is assuming you glyph for UB and not DC. I was not basing it off that glyph. However with the glyph and finding a way to get UB it is a better choice. Dropping a point in BCB for UB then glyphing UB is probably better however I still feel that 10-10-51 works. I know I gain 450 ap and 24 RP per minute. Losing 40% damage on diseases (assuming 40% melee crit raid buffed) and 20% damage on white attacks in the process. Yet the 450 AP applies to both as well as to everything else.

I changed my spec and my UB ticks for 270 with only HoW. The real question is at what point would I drop Sigil of the Vengeful Heart for Awareness.

edit: It would appear as though Awareness has taken over Vengeful Heart, it makes me sad inside.
