Actually, I'm fairly sure this isn't true. Immolate does X damage over 15 seconds, ticking every 3 seconds for x/5 each time. Conflag hits for 4x/5. The glyph makes immolate hit for 1.1x, and therefore tick for (1.1)x/5, and conflag hits for 4 * 1.1 * x / 5. In other words, the glyph makes your immolate ticks hit 10% harder, and therefore your conflag will hit 10% harder than it did before. I could be wrong, I've never tried to run the numbers on it, but the text of the talent, skill, and glyph all indicate to me that it's a 10% boost.

Q: In a 25-man raid that has no elemental shaman and 5 other DPS casters (for a total of 6), is it a no-brainer to spec demonic pact for overall Raid DPS? There are regular shaman around (for flametongue totem), but I'm looking at something on the order of a 210 spellpower buff over flametongue from my demonic pact build.

The rDPS thread seems to have evaporated, but all I'm looking for is a rule of thumb about when it's worthwhile to activate my 56/15 spec over my 13/58 spec for 25-man raids.

simple formula:
personal dps loss < SP gained * raidmembers effected * uptime * DPS/SP

If you loose about 1000 DPS and give additional 200 SP with 90% uptime and an average DPS/SP of 1.25, you will see a benefit with 5 other DPS caster in the raid (200*0,9*1.25=225 *4=900 *5=1125) and this is not yet accounting the effect on your healers.

Replace with your own numbers at will.

what are the best stats for destruction at the moment, for example 500haste, 21% crit thats without raid buffs. what would be the better to gain crit or haste with those stats

Your guild or character don't seem to exist on the Armoury so I cannot comment.
Generally speaking, assuming raid hit-capped, Haste is a far stronger stat for Destro, weighing very similarly to spellpower. Stack Haste and SP.

Isn't stacking haste and spellpower pretty much the way to go for each spec? Crit has a budget cost far too high per point to be worth it, and spirit can't compete either.
Although I agree with you that for some specs it's "stack haste, then spellpower" (like for 0-41-30, since it already has a lot of spellpower), while for other specs it's "stack spellpower, then haste" (one day dots will scale with haste....one day....).

Indeed. We're pretty much singing from the same song sheet here. I didn't really list them in any specific order. I believe crit is important to DP meta spec for keeping the buff uptime high. Spirit is still important for anyone who may still running the 4T7 bonus and LT glyph.
The important thing to remember is that the weights of the various stats depends on what you are already wearing.
For example i run with about 2.1k unbuffed SP 19.5 crit and about 610 haste atm. I feel that I'm quite loaded with haste and would probably opt for spell power items if given the choice.
DoTs scaling with Haste really throws the dog amongst the Squirrels. I'd love to see it happen

When warlocks say "unbuffed", does that mean with Fel Armor on or off? I realize that the question itself seems obvious, but I've read many messages in WoW with warlocks saying "2500 SP unbuffed" which seems to be a bit too much even with the best Ulduar gear without the Fel Armor.

I usually take that to mean with fel armor, but without any other buffs such as food, flasks, or totems, although you can probably get that high with a demonic knowledge build and no fel armor. Maybe.

ISB Vs. Scorch (Help Please)
Alright. There have been plenty of times I have bounced something off one of your member's shoulders, and have been presented with amazing feedback and information. This time, I have to up the level, and really dig for what I want.

The argument at hand;

"When considering a Warlock and a Mage(2) in terms of DPS loss, which comes out ahead when faced with who to assign ISB/Scorch?"

Its been a long standing argument between our Mages and Locks. Currently we have a warlock who specs into ISB to provide the debuff for our casters. Now, from what I am seeing he is either plagued with one of the following;

Parse below is with our ISB warlock (Forsakensake).

1) Lowered DPS due to a gimped spec (Is that possible with ISB or should he still be putting out significant numbers)
2) Just a bad player.

Now I am under the assumption that the mages lose less DPS than a warlock when speccing into the equiv (Scorch). I should also add we currently run with three mages. Having 1 spec into scorch would not be a terrible idea. However it is also an option to have them rotate.

Now, this all came to light when I compared Fosakensake's performance as destruction (Which will always come ahead of ISB I am assuming) to his performance as ISB.

Questions I am looking to have answered;

Is it possible for him to do better as ISB?
What losses do the mages suffer from speccing into scorch?
How does it compare?
How do you guys handle this debuff, and what were your experiences in figuring out which was more beneficial?

If it is fast to die trash then rain of fire should be more effective in damaging quickly. If it is higher health trash that takes a while to die then seed of corruption should be more effective. Generally seed requires more than 4 targets to allow you to get continual seed explosions. Seed will give you, as an affliction lock, a higher damage return, but it takes longer to get the damage started.

Rain of fire crits and depending where your gear and spec are at, this could swing the balance in favour of rain of fire damage.
