No... as I said, I just blindly plugged my numbers into the one's Blacksen provided above. It is not a 10% increase in DPS, it's not even close. My SB DPS is 1528 unbuffed.

(3900) / (2.5*(1-.1055)*((1490 + 722*3) / 127))

which is 64.4 DPS

Shadow-bolt calculation should be halved, but the outcome should be similar. It's definitely Immolate + Siphon Life. The 3rd glyph is up in the air.

While Mathematically, Shadow Bolt will come out higher, it isn't necessarily practical. The value of an instant-cast Shadowbolt in terms of your DPS is pretty interesting when you get into Drain Soul range and work to keep Shadow Embrace up, or in fights which insist on movement. The last thing is that you don't get that Shadowbolt DPS until you've saved yourself a life-tap. In shorter fights, this won't really ever occur.

So I switched my glyphs around to Corruption, SL, and Immolate, and have definately seen a nice increase in my dps and immolate and siphon life damage. I'm still curious though, is immolate a for sure dps increase from coa glyph? I'm raiding a heavy affliction build and am trying to maximize my dps as best possible.

Yes. Both Immolate and Siphon Life Glyphs are way beyond the DPS you get from CoA.

Interesting read about Glyph of Curse of Agony being so terrible. That is quite unfortunate.

Corruption, Siphon Life, and Immolate. These are the best glyphs for PvE, sadly not because they are so good, but because everything else is so terrible.

WTB more/better Warlock glyphs Blizzard.

Especially for Destruction. The amount of beneficial glyphs for that tree is laughable.

Given the lack of Destruction-oriented glyphs, I would imagine CoA could be used.

A cursory glance would lead me to Immolate, Imp, and Corruption glyphs, though.

I may be totally off on this (since I've been playing a lot of Affliction these last days) but I would say that if you're going for Backdraft, the best glyphs would be Imp, Conflagrate, CoA. If not, then Imp, Immolate, CoA.

My thoughts: You spend a lot of talent points in improving Immolate and mostly it's initial damage. If you also use Conflagrate (which clips the last or even 2 last if you use it too early which can happen) why would you want to decrease the initial damage and increase the DoT? Conflagrate may not be the best one out there but considering how mana heavy Destruction is, it might save in something for you. However, this may be as crappy as Glyph of Shadow Bolt considering how little you use it. CoA obviously since it allows you to cast more Incinerates.

When it comes to Corruption... I've never really used it playing Destruction. I'm still not convinced that it's worth putting up as well, unless I see some solid proof.

Yeah, when I was deep destro spec, I only used corruption for MC uptime if I had to cast any other curse. But the preferred was definitely CoA.

In regards to clipping two ticks of immolation: no amount of spec or glyph can make up for bad play.

As for Conflagrate, you save only 120 mana every 15 seconds, or 8mp5. Without even doing the math (you can look back in this thread to see similar calculations), you can see that wont amount to any meaningful increase.

While I agree that corruption may not be the greatest of glyphs, there aren't any superior alternatives.
Destruction has Imp, Immolate, Shadowbolt, Conflag, Corruption, and CoA as its primary glyphs. Searing pain and shadowburn aren't worth mentioning. Given how fire-oriented destruction is, shadow bolt is only used via corruption glyph procs. The math for the shadow bolt glyph was also done earlier in the thread and found to be fairly awful. CoA was one extra GCD per 168 seconds and saves 361 mana (w/ Suppression) over that same interval, or 2.14mp5. That GCD saved translated to about 60% of a shadowbolt's damage for + (.6 * SB_Damage)/168 dps. With an SB hit of 5000 that's 17.85dps.

You can really just look back to page 4 to see the majority of glyph calculations. I think you may be right is with the immolate glyph, but I'm getting tired at moment, so I'll check later.

Hopefully I didn't bork any math from fatigue.

Well, there's two cases for Destro warlocks: either you're conflagging or you're not. Let's look at both cases.
Base Immo does 460 + 785 over 15s, for a total of 1245. All destro locks will have improved immo, which makes it 460*1.3 + 785 = 1383. Conflagging warlocks will have 460*1.3 + 785*0.8 (they lose the last 3 second tick) = 1226.

With the immolate glyph:
Plain: 460*1.3*.9 + 785*1.2 = 1480 damage over 15s, or +6.5dps at +0 spell power.
Conflaggers: 460*1.3*.9 + 785*1.2*.8 = 1292 damage over 12 seconds, or +5.5dps at +0 spell power.
In both cases, a net dps increase.

In exchange for the shortened immolate (and a GCD), the fully-talented conflag lock gets 860 damage at +25% crit, possible soul leech proc, and 30% off your next three destro spells (which if they are immo (2s), incin(1.75s), incin(1.75s) saves you 1.5s , or a GCD)

As shown in previous posts, Glyph of CoA gives you a GCD every 168s without increasing dps. That's an extra incinerate every 196 seconds. Woo. As my post showed, Glyph of Conflag saves you a GCD every 281s or worse.

Around 4k+ on Patchwerk type fights, but I have lot to improve. For one my ISP (according to quartz) shows 200-500 ms during this fight. I know you can chain spells, but it's different when your actually "there"

I'll post our guilds WWS after we clear all 25 man instances here so you'll get some grasp.

I updated the first post to where the discussion is at right now (up to post 114). Please check it out for where more holes need to be filled in. Also, please let me know if I messed up somewhere or missed a post. Please remember that I did try to filter out the more speculative posts as well as the posts with wrong math. I apologize for not doing this sooner, I'm in the middle of finals.

Also, may I request a consensus of assumption stats? So far I have it at: +2000 SP, +20% Crit, 3500 DPS (stationary), and 4000 Shadowbolts.

Can you tell how did you get bolded numbers?

Just as a note for the original post, which is turning out to be one of the better thread-openers I've seen around here (keeping it updated & informative FTW)- you have Glyph of SL listed under the destruction build. I don't really know what's a better given glyph, maybe Imp? Maybe CoA, maybe Corr, maybe Conflag works, but regardless, glyph of SL shouldn't be under destruction :P

Ah that is my bad. I've updated the first post now to correctly reflect the thread progression.

I see some speculation that the ua glyph is not worth using and the reasoning for this is b/c it's not going to go lower than the gcd, but on just using this glyph for a couple of days before reading everything and switching to immo, corr, and siphon for deep affliction, I can't help but feel that this glyph did make this spell cast significantly faster and there was no extra time added on to make up for a 1.5 gcd. It simply cast .2 seconds faster and I could cast another spell immediately. We already know the gcd can't go below 1 sec, so why do we assumed this glyph is absolutely worthless. Perhaps it can't lower the gcd below 1 sec and 1.5 secs is the wrong thing to be looking at here. My haste was setting at a place where I was casting ua in approximately 1.15 seconds with no penalty being added to bring me up to a 1.5 second gcd.

I'm probably just missing something blatantly obvious that discounts this glyph, but any speculation or actual math would be of tremendous help. It seems foolish to make a glyph that is this worthless to begin with if it can't lower a 1.5 second cast below a 1.5 second gcd.

Ravenelle, just calculate how long the fight would have to last for you to gain even one extra shadow bolt cast.

with your haste + glyph taking you down to 1.15 cast time on UA, wouldnt your GCD be 1.35 instead of 1.5 as you insist of using.

About the CoA glyph (for a demo/destro lock), you must take in consideration fights in which you switch targets.
For example, you dps Anub'Rekhan till Crypt Fiends come and then dps them down.
2 more ticks of CoA on A'R while you are on adds aren't huge dps wise, but are however an additional chance to proc MC.
Same thing with Gluth while you're using Rain of Fire on zombies after Decimate and so on.
The math done that shows how a glyphed CoA isn't a direct dps increase stay valid on bosses like Patchwerk, but in more dynamic fights it may help a bit (for MC uptime, at least).

I am deep destro build, 0/20/51. I'm using Corr/Imp/Immolate but would like to change to CoA/Imp/Immolate as soon as I find a CoA glyph. My question is what minor glyphs are helpful? I'm currently using the Drain Soul to make shard farming slightly easier, but it doesn't seem to proc very often. I have the healthstone glyph, but am at a loss as for a reasonable 3rd minor glyph might be.

Last I checked Healthstone is a major glyph

Really, we don't have relevant minor glyphs for raiding. Go with whatever you want. To be honest, in my opinion our most useful minor glyph is... Unending Breath. WotLK has a lot of quests that involve swimming, and that makes it slightly useful. But, again, obviously useless for raids.
