My Spirit at 14% hit is 688 so I get 137.6 * 1.57 = 216 dps out of 1 GCD per 40 seconds. 1.5/40 = 3.75% of my time.
216 / 8066 (the calculated dps of 0_13_58) is 2.68%
So for me, at least, the boost in Spell Power is not enough to overcome the loss of even 1 GCD every 40 seconds.
Now for situations where you never actually get the perfect timing, it might turn out to be a boost, especially for Affliction in a high movement fight where the SP is boosting your dots even when you aren't casting.
You're assuming you have 0 haste and 0 need for lifetapping. Look at it this way:
The Damage per execution of LifeTap = 688*0.2*1.57*40=8641
The Damage per execution of Incinerate using BiS gear of Incinerate = 10048 according to the Simcraft thread.
The cast time of lifetap is ~66% the cast time of incinerate, and the damage is clearly more than 66% of an incinerate- so the DPSC is clearly higher. Plus, you'll have to lifetap anyway- so it's silly to assume that you're just wasting the GCD for nothing.
It'll still take some extra time to figure out wether or not that makes Glyph of Life Tap Better than glyph of immolate/incinerate, but I have a hunch that it'll be better.

Running Simcraft on my own character with patch=3.2.0 shows a dps increase of ~50 when using Lifetap glyph over Immolate. Using Lifetap in place of Incinerate is a dps loss. This is all using a cookie cutter 13/58 spec with replenishment. So it seems that every raiding spec will use a Lifetap glyph again. 13/58 will trade Immolate for Lifetap, and 3/13/55 will stay the same.

Just a clarification, are you running T8 gearsets or T9? The T9 4-piece bonus (10 percent increased immolate damage, which will then increase your conflags) makes me wonder if this would still be the case at that gear level.

The T8 gear set also adds 10% to immolate, so that should not make a difference in the outcome.
I was wondering if anyone could point out why when I use Leulier's for Demo spec (0/56/15), it shows Glyph of Metamorphosis much higher than Glyph of Immolate? Perhaps this is the wrong thread to ask on ^_^ but how much dps difference do sims show for the two glyphs?

In the past (not sure if this is still true) the difference was very small, in the realm of "not worth changing" (around 10-30 dps or whatever).

Note that the higher uptime due to GoMetaorphosis will be a more substantial DPS gain on fight with "burst phase" mechanics (XT, Yogg) and fights with long wait times between phases (where meta will be up for more of the actual DPS time) - ie. Mimiron. I use it, and I find it provides a better gain than the flat damage buff, but that's just personal preference.

I'm not sure what burst phase you're referring to on Yogg (Stun phase doesn't really have that effect), but it would do nothing for XT, seeing as the heart is only exposes for 30 seconds. Likewise however glyph of Meta loses value if you dont pop meta on cooldown.

Hmmm... So assuming you Lifetap once every 40 seconds on a 13/58 build is it safe to assume you'll have a dps increase when comparing to immo glyph? From my experience I very rarelly have to lifetap to regain mana, so I would only be doing it to proc the glyph. Is it really worth it? I'm not so sure....
Ah! Thought so... Wouldn't make much sense loosing one GCD every 40 seconds... Didn't seemed at all like a dps increase.
So for 13/58 warlocks, besides the talent changes, nothing else changed? Same rotations, same glyphs. Only thing I did was upgrade my gems to epic. Or am I missing something?
If you skill ISL you skip on the LT Glyph - even after 3.2. improvement.
Wouldn't be too sure about that. I'd say it depends on your current spellpower to spirit ratio, and that the actual answer for whether or not to use the LT glyph can vary a lot from player to player.

I ran the latest simcraft (r3021) against the 0/13/58 (ISL) profile with modified glyphs:
These results would imply that switching the immolate glyph out for the llife tap glyph would be a DPS increase when even specced into ISL. Please do note that I did not specify a rotation. I am uncertain whether simcraft automatically chooses a suitable life tap rotation when overriding the glyphs.
I am specced ISL and I switched from GoImmolate to GoLT last night and wasn't impressed with the results. While my base spirit (594) isn't particularly high, it was more the inflexibility of timing my taps for the buff rather than with movement or between phases that hurt my dps. I suppose with more practice I could raise my LT up time without wasting the globals, but I feel that most encounters allow chain LTs between phases or while moving that would result in wasted buff time.
I've noticed the same thing Demi9OD. After doing some calculations of Incinerate vs Immolate, I've also noticed that dropping GoIncinerate for the GoLT might be a better choice. I suspect this is due to the nerf to Incinerate while neither Immolate nor Conflag got nerfed.
As of right now, I'm still skeptical as to the benefits of LT over either of the Glyphs. From calculations, the dps gain for the LT glyph requires approximately 83% uptime to be on par with Incinerate. (Going with 600 spirit, which seems to be in line with most people in Ulduar 25 gear.)
In a patchwerk-style dps fight, yes the results are close, at least within < 1% of dps.
But, in a more realistic fight involving movement, and having the ability to LT (Rank1) just before the pull, I'd think that the LT glyph would easily surpass Immolate. Not to mention that you can use it like an activated trinket for bosses that take increased dmg at times. All of the qualitative factors put LT way ahead of Immolate in realistic scenarios.

No it doesn't, so the glyph buff in your run was only up for like the last half of the fight, and even then it was a small gain.
Try putting actions+=/life_tap,glyph=1 above your other spell actions.

The syntax has changed, I used actions+=/life_tap,buff_refresh=1,moving=1 instead.

EDIT: Morrigan (below) is correct, the new syntax isn't working correctly. Consequently my results are not trustworthy.

That's because the new syntax isn't working correctly. Do combat_log=1 and search for the first occurrence of "life_tap", you'll notice that it is several minutes into the fight, i.e. it doesn't tap before you run oom.
With r3005 and actions+=/life_tap,glyph=1 you get at least a ~70dps increase over glyph of immolate, which should be closer to reality.

The syntax is working correctly. The problem is with the auto-gen of the action list. (We've moved to using wowhead profiler for our golden configs which requires we make the default action generation smart enough.)
EDIT: I sit corrected: There most certainly IS a bug here.
EDIT2: Fixed in r3040. I'll regenerate the SampleOutput and put out a new release.
