I just want to ask two things:
1) Assuming i have both corruption and immolate on my target, does the effect from the 2 tier7 set bonus proc's with both dots ?
2) And assuming it does. is it worth it casting immolate on target with 0/53/18 talent spec?

Thanks for your time.

1) Both Immolate and Corruption will proc the t7 two piece bonus. One alone should be enough to keep a good uptime. But, you want both on your target with that spec anyway.

2) Immolate is still a dps increase for that spec. Assuming the last three points spent in destruction are Cataclysm, you could swap them out for a point or two in Molten Core as you get more hit on your gear, increasing the dps of both Immolate and your Immolation Aura when you pop Meta (assuming MC procs then, it won't always).

As the above poster said, immolate is worth casting regardless.

As for Molten Core, I don't recommend more than 1 point in it, since fire isnt a huge part of your damage, and you'll be able to have very decent uptime either way due to the fact that you're using shadow bolt as your filler.

I'm not so good in knowing other classes, but i was wondering, from which point it makes sense that a damon warlock goes after Demonic Pact. Atm we have max one shaman in our raid, and as far as i know, the +spell dmg totem is not the only usefuall one he has.

There's no 100% uptime for demonic pact. What i don't know is how to actualy calculate the crit-rate of my demon. I can't find those in the stats of my demon.

it's clear if there's no shaman in the raid, demonic pact is usefull. What i'm more interested in is, if there's only one shaman in the raid, does it help ith the warlock does demonic pact and the shaman uses another suitable totem (assuming that the demonic pact isn't stronger then the shaman totem anyway). What leads my to my second question: is there a formula to find out at which point demonic pact is overall better then the totem. ( 2800 spell dmg won't be enough because there's proablay no 100% uptime.)

I am usually around 29% crit buffed and I have imp demonic tactics to give the pet 30% of that on top of his inherited crit and the uptime of demonic pact has been over 90%, like between 92 & 95 %. Right now you can't count any spell damage that you get from spirit through fel armor because demonic pact is bugged and that spell power is not being counted toward the buff. So you would need 2800 or more spell power not including what you get from spirit for your buff to be higher than the 280 buff from the shaman totem. Since the uptime is so high and especially if you are well beating the 280 then your buff will be the better buff. It's doable in current gear, will be incredibly easily doable when they fix demonic pact as they have said they intend to and will only continue to scale as we go into Ulduar as the shaman totem does not scale and demonic pact does.

I am sorry if this is already covered but i would like to ask does 0/53/18 beat 0/41/30 at higher gear levels? Also if there is an elemental shammy in the raid would it be better to go 0/41/30?

Small correction, meta is a 20% buff to damage.

Is there a consensus as to which meta gem is the best for a Meta/Ruin spec? Chaotic Skyflare or Ember Skyflare?

Easily [Chaotic Skyflare Diamond]

How certain of that are you? 21 crit rating vs. 25 spell damage, and the 3% increased crit damage isn't going to be tripled to 9% of base damage as it is by Devastation in a Destruction build. I'm not saying that 2% INT is that compelling--but at least at my level (intro 10-man Naxx), I'm pretty sure that 25 spell damage and 2% INT rather handily beats 3% increase to the relatively few crits I actually land.

Your thoughts?

Isn't it Ruin that provides the 9% boost?

Grabbing some maths from the spreadsheet thread:
All Devastation does is provide an extra 5% chance to crit, (and a Meta/Ruin build already has 10% crit from Demonic Tactics) and it's generally agreed that caster chance to crit is currently high enough in a 25 man raid to devalue crit rating.

Maybe I'm misunderstanding something, but I don't see why missing 5% crit chance reduces the value of CSD.

Got a question about hit rating, does 1 spell power gain me more than 1 hit rating.

I'm specced 0/50/21 with Demonic Pact since we don't have a raiding elemental shaman in our guild. Got really good gear but are low on hit rating, and even worse if there is no spriest or boomkin in the raid. I read somewhere before about 1 SP > 1 HR for boomkins but that post got voted down because if certain spells miss it would lower the DPS, a warlock example would be if an affliction specced lock missed his Haunt cast. But for me which doesn't use any spells which ups my other spells DPS I can just ignore hit rating? or should I get more hit to increase my DPS.

Armory: The World of Warcraft Armory
WWS from PW: Wow Web Stats
Trinkets on Armory isn't what I use in raids, I use Dying Curse and Illustration of the Dragon Soul.
No flask, buff food or potion was used during that raid.
The spells I use: Corruption, Curse of Agony, Immolate, Shadow Bolt.
Glyphs: Immolate, Corruption and Felguard.

Atm I'm happy about my DPS, 4829 DPS on Patchwerk is in my opinion high for a Demonic Pact warlock or am I wrong? And when I'm posting anyway maybe someone see some other room for improvements in my spec, rotation, gear, enchants or gems? One thing for sure is that I still need to have Demonic Pact in my spec.

0/53/18 or 0/55/16 would probably perform better- also hit is definitely superiour to spellpower until capped (289 with boomkin/spriest).

You got any math on HR > SP for demo locks? And also the build you posted does those include Meta?

The thread from where I read about SP > HR for moonkins: Spellpower > Hit

The calculations in that thread are only about Wrath's damage per cast. It doesn't take into account anything, like other abilities, talents, etc. As such, it's not an accurate representation of DPS gain for the two gems.

For example:
A Faerie Fire resist would deprive the raid of 3% hit for a GCD.
A Wrath/Starfire resist would deprive the raid of 13% damage for another cast length
Wrath/Starfire resists increase the time to an Eclipse proc (which greatly increases DPS).
A missed spell can't crit, which means no chance of a Nature's Grace proc (which greatly increases DPS).
A missed spell can't proc Omen of Clarity, which means more wasted mana.
And probably more.

None of these things are factored into the linked thread. You really can't look at just spell damage+coefficients anymore.

Hit is so important because for a lot of classes/specs, the raid is depending on a debuff or a proc. Under cap hit rating means that a spell may resist where it would have not previously, costing the whole raid DPS.

For numerical proof, simulationcraft would be your best bet.

Yea I know exactly those things you just said, I posted that 4 posts up. For most dps classes HR > all but I'm starting to doubt about demo locks. The thing is that warlock spells (in my case Corruption, CoA, Immolate, Shadow Bolt) doesn't help increase raid dps. Maybe Immolate for destro locks at best.

Using Leulier's spreedsheat, but find some things weird, for example it says I will gain DPS by switching belt to Cincture of Polarity, but if I change it and calculate again it says I will gain more DPS by changing it back, that's why I posted here to maybe get some help on the matter.

Unless something has changed, spells use a 2-roll system unlike melee.

Spell hit - WoWWiki - Your guide to the World of Warcraft

This is really what's wrong with a lot of people in my opinion- don't get me wrong I'm not talking about you specifically- but a lot of people simply believe things just because it's the general concensur that it is true. Also missing 1 wrath or starfire shouldnt result in earth and moon downtime- those are their main nuke. It's much like a single shadow bolt miss will probably not result in ISB downtime for Meta/Ruin specs.

It's an interesting topic really, though I dont think he is correct (its just a shame no one went though the math to prove it).

So lets take shadow bolt for meta-ruinj: 690-770 damage (730 average), 3/3.5 co-efficient, 2.5s cast time, 50% crit, 99% hit and 3000 spellpower raid buffed.
Modifiers:
- 13% earth and moon
- 3% Sanct ret
- 5% MD
- 3% demonic empathy
- 9% (90% ISB uptime)

(730 + ((3/3.5) * 3000)) * 0.99 * 1.13 * 1.03 * 1.05 * 1.03 * 1.09 * (1 + (0.5*1.09) / 2.5 =
Simplify:
(3301.43) * 0.99 * 1.13 * 1.03 * 1.05 * 1.03 * 1.09 * (1.545) / 2.5 = 2771.36 DPS

Now lets add 19 spellpower:
(730 + ((3/3.5) * 3019)) * 0.99 * 1.13 * 1.03 * 1.05 * 1.03 * 1.09 * 1.545 / 2.5 = 2785.04

Lets add 16 hit instead:
(730 + ((3/3.5) * 3000)) * (0.99 + (16/26.23/100)) * 1.13 * 1.03 * 1.05 * 1.03 * 1.09 * 1.545 / 2.5 =
Simplify:
(730 + ((3/3.5) * 3000)) * (0.9961) * 1.13 * 1.03 * 1.05 * 1.03 * 1.09 * 1.545 / 2.5 = 2788.44

So apparently for shadow bolt, 16 hit still beats 19 spellpower.
Other spells like immolate are a lot harder to do, because essentially missing an immolate doesnt mean you reduce your damage by ` immolate, instead you reduce your damage by 1.5/2.5 (60%) of a shadow bolt, and 1.5 second immolate uptime (more if you do not immediatly cast another immolate after you miss your immolate, and you'd probably not immediatly do it so you'd get closer to missing ~4 seconds of immoalte uptime (which equals the damage of 1.33 ticks).

It gets even more complicated when you try to castor haste in due to the fact that you'd have to factor it in differently for the shadowbolt damage lost and dot time lost.

If you still want the math on that, I might be able to provide it later. But quite frankly;
you gained 13.68 DPS on shadow bolt from 19 spellpower, you gained 17.08 DPS from 16 hit- seeing as shadow bolt is such a massive part of your total cast time it should be fair to say that hit wouldnt catch up through immolate and corruption cast misses.

I stand corrected, thanks!

Just to be absolutely precise; from the theorycrafting thinktank.

One roll vs Two roll

The majority of melee attacks made in WoW use a one-roll system. This means that a single check is made against the hit table to determine the outcome of an attack.

Some special attacks (notably all Rogue special attacks) use a two-roll system. The first roll first checks to see if the attack lands, misses or is avoided. If the attack lands, the second roll checks to see if it hits or crits. Two-roll attacks are observed to be similar to one-roll attacks in all other manners.

This can be proven by using an ability with a very high crit rate against a target that has an ability that decreases the player's ability to hit. For example, Attumen's Intangible Presence debuff decreases the player's chance to hit by 50%. If Backstab had a 60% chance to crit and used the one-roll system, all hits while under the effect of Intangible Presence would be critical hits (since crits override normal hits in the hit table). This is not the case, so it can be deduced that the crit chance is rolled separately from the avoidance check.

As for hit versus dmg, we have SampleOutputCaster - simulationcraft - Google Code for providing easily accessible scale factors for a variety of specs and it only lists some of the affliction variants as having a higher DPS gain from 1 sp versus 1 hit. However the difference is so marginal that no one would risk a missed haunt.

I guess something bugged on Razuvius tonight, my felguard made a 92k swing. Anyone ever seen this?

Nope, never noticed any absurdly high swings, although I must say that's pretty awesome.
