Affliction Raiding How-To Guide! (part 1)

Welcome to the first post of the Fallenman & Clearly warlock blog! We decided to create this blog, so that people would have a central location to see anything they find useful posted by us. We will still be doing forum posts with most of our blog entries, but this gives people a go-to repository of information!!

The first posts here are about Affliction Raiding. This will answer very common questions such as these: Should I use immolate? Should I drop any DoTs from my rotation? What is the rotation? My DPS is really bad, what am I doing wrong? How can I get better at affliction? This will be broken up into 2 posts. The first, below, dealing with DPCTs and whether or not you should be casting all of your DoTs.

I'll start by clarifying what DoTs should be used. The answer simply is, ALL of them. This includes immolate! Affliction is all about efficient use of the Global Cooldown or GCD. If you're not constantly casting something, then you're losing DPS. (this is true with any spec really) But, with affliction, that loss is more noticable. Because affliction is so dependent upon efficient GCD usage, one of the most important things to know for any affliction warlock is called DPCT. (Damage Per Cast Time)

DPCT is a measure of what you get in return for the amount of time used to cast a spell. For example. If you cast a shadowbolt, and your shadowbolt's average damage is 1000, with a 2.5 second cast time, the DPCT is 1000/2.5 or 400DPCT. If you cast a DoT that will do 1000 damage (no matter how long it takes to do that damage), and the DoT is instant cast, then the DPCT is 1000/1.5 or ~667DPCT. (instant casts "time used casting" is whatever the length of your global cooldown is)

So, what does this mean to an affliction warlock? Simple. Shadowbolt is your "filler" spell. IE, it's what you cast when your dots are ticking and none of them need refreshing. You fill this gap with shadowbolts. That said, any dot that has a higher DPCT than your filler spell (shadowbolt) should be cast, because it will mean more dps for you. This is because you get more damage for the amount of time spent casting the spell than you would casting a shadowbolt.

---------------------------------------------------------------------------------------------------

Below, I have listed out the DPCT for all of an affliction warlock's spells, using (22% crit from gear) 40% crit rating, 2000 spell power, and hit capped. This assumes a 56/0/15 build, and the stats are AFTER raid buffs have been applied. (build: http://www.wowhead.com/?talent=IbxMbuMAoqA0IstZE00V)

Corruption:
1080 base damage + ((120% coefficient + 36% empowered corruption + 30% everlasting affliction) * 2000) =
1080 + (1.86 * 2000) = 4800 base damage.
Modifiers:
4800 * (10% improved corruption + 15% shadow mastery + 5% contagion) * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) * 20% haunt * 10% shadow embrace =
4800 * 1.30 * 1.03 * 1.13 * 1.03 * 1.20 * 1.10 = 9874 modified damage.
Pandemic: 9874 * 1.22 = 12046
12046 / 1.5 second GCD = 8031DPCT

Curse of Agony:
1740 base damage + (120% coefficient * 2000) =
1740 + (1.20 * 2000) = 4140 base damage.
Modifiers:
4140 * (10% improved CoA + 15% shadow mastery + 5% contagion) * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) * 20% haunt * 5% shadow embrace =
4140 * 1.30 * 1.03 * 1.13 * 1.03 * 1.20 * 1.10 = 8516 modified damage.
8516 / 1.0 second GCD (amplify curse) = 8516DPCT

Immolate:
(460 base DD damage + (20% coefficient * 2000)) + (785 base DoT damage + (100% coefficient * 2000)) =
860 base DD damage + 2785 base DoT damage
Modifiers:
860 base DD damage * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) = 1031 modified DD damage.
(crit factor) 1031 modified DD damage * 1.40% = 1443 total DD damage.

2785 base DoT damage * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) * 20% haunt * 10% shadow embrace = 4407 modified DoT damage.

1443 DD + 4407 DoT = 5850 total damage.
5850 / 1.5 second cast time = 3900DPCT

Siphon Life:
810 base damage + ((100% coefficient + 50% everlasting affliction) * 2000) =
810 + (1.50 * 2000) = 3810 base damage.
Modifiers:
3810 * 15% shadow mastery * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) * 20% haunt * 10% shadow embrace =
3810 * 1.15 * 1.03 * 1.13 * 1.03 * 1.20 * 1.10 = 6933 modified damage.
6933 / 1.5 second GCD = 4622DPCT

Unstable Affliction:
1150 base damage + ((100% coefficient + 25% everlasting affliction) * 2000) =
1150 + (1.25 * 2000) = 3650 base damage.
Modifiers:
3650 * 15% shadow mastery * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) * 20% haunt * 10% shadow embrace =
3650 * 1.15 * 1.03 * 1.13 * 1.03 * 1.20 * 1.10 = 6642 modified damage.
Pandemic = 6642 * 1.22 = 8103
8103 / 1.5 second GCD = 5402DPCT

And finally,
Shadow Bolt:
730 avg base damage + (85.7% coefficient * 2000) =
730 + (.857 * 2000) = 2444 base damage
Modifiers:
2444 base damage * 15% shadow mastery * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) = 3369 modified damage.
ISB factor = 3369 * 1.085 = 3655. (this assumes 85% uptime which is inline with 40% crit rate)
(crit factor) 3655 modified DD damage * 40.0% = 5117 total DD damage.
5117 / 2.5 second cast time = 2046DPCT



So, as you can see, ALL of your DoTs should be cast. You can use the above formulas to plug in your own stats, including haste, crit, and spell power. For crit, without ruin, you simply cut your crit rating in half, and insert that % into the above formulas. For haste, simply change the cast time to match your cast time. :)
