EDIT: Revamped to reflect Patch 5.0.4
Basic Tips - If playing Demonology, take Grimoire of Service. If playing Affliction, take Grimoire of Sacrifice. Try to avoid Destruction as it doesn't play to the standards of Demonology or Affliction.
Morchok - Demonology/Affliction
Affliction - Perform your rotation as you would normally on your primary target. Use Soulburn: Soul Swap to instantly place all 3 DoTs on the boss you are not assigned to and apply your DoTs one by one on your primary, assigned target. Nothing else fancy here.
Demonology - Perform your rotation as you would normally on your primary target. Have your Felguard(s) Felstorm on cooldown and try to time every 3 of their Felstorms with your new Demon Soul cooldown that grants Mastery rating. If a Stomp comes and you're in Meta form, feel free to take a double share...you'll take less than the tank.
Yor'sahj - Demonology preferred
Overall Warlock Tips: Use your Infernal during a Black Ooze combination. If coupled with the Demonology strat detailed below, you can darn near solo all of the adds. Remember to use Life Tap ONLY after the Mana Void has taken everyone's mana. Since your raid will be dealing with the Purple Ooze a lot, you don't want to put yourself in the bad eyes of your healers. Tap once and only once...your mana will be restored when the Void pops or when your Demon crits.
Demonology - Demonology has no competition on this fight if 1 single Black Ooze comes in contact with Yor'sahj. For any AoE situation, tell the rest of your raid to focus on Yor'sahj while you melt the adds as if you were a torch flame and the adds were like warm butter on a hot summer day. Simply enter Metamorphosis form, use Grimoire of Service to summon out a 2nd Felguard, use Hand of Guldan on Yor'sahj, apply Immolation Aura with Hellfire, use 2x Felstorm, and use Void Ray for about 6 seconds. Enjoy your stay at the top of the meters and pray for more black phases. If a black phase comes and you don't have Service off CD, simply use your Infernal in place of Service.
Zon'ozz - Affliction/Demonology
This fight change greatly depending on assignment, but you will likely be assigned to kill Eyes and Flails. Due to Destruction's ranged pet, on-demand burst, and Nether Protection, you will most benefit your raid as a Destruction Warlock. If you are assigned to stay on the boss, you can go Demonology (bonus if your raid leader puts you in the melee group).
Affliction - Multidotting Eyes and Flails will boost your DPS, but it will add strain to the healers unless you are not assigned to kill a particular set of Eyes/Flails. To do the best burst as Affliction, use Soul Swap to take out the first Eye/Flail you are assigned to. Be prepared for MONSTER Drain Soul ticks when Zon'ozz is below 25%. Time your Grimoire of Sacrifice for when you are performing your execute of Zon'ozz (sub 25%)
Demonology - Offer to kill adds, but let your raid leader know your DPS will be significantly higher if left on the boss. Your Felguards should never have to travel from add to add, so keep them on the boss. Either get teamed up with a high burst DPS for adds or just wittle away at yours for a while. Use Felstorm on CD and perform your normal rotation.
Hagara - Affliction/Destruction
Your success on Hagara depends on your ability to switch targets fast and get your DoTs up faster.
Affliction - Affliction's new Soulburn: Soul Swap is incredible for quickly applying DoTs to Hagara during Feedback and getting the Ice Crystals down ASAP. For mind-blowing numbers, as soon as the 4th Ice Crystal dies, use your Grimoire of Sacrifice, Soulburn: Soul Swap your 3 DoTs on Hagara, and begin channeling Malefic Grasp...try to contain your excitement of huge yellow numbers popping up on your screen.
Demonology - Perform your normal rotation. Time Grimoire of Service when Hagara suffers Feedback. Two Felguards recklessly shredding Hagara's face at double damage will make you perform quite well. Popping Meta and getting into the fray will likely draw an Ice Lance attachment your way, so be prepared to call out for an intercept or use someone standing still as a human shield for a few seconds.
Ultraxion - All specs viable.
Perform your basic rotation no matter what spec. Just don't die to Fading Light. You can now successfully eat an Hour of Twilight with Dark Bargain. You'll require a bit of TLC after Dark Bargain wears off, but it's nothing your healers should automatically deal with since they will be spamming AoE heals.
Warmaster - Affliction
Any other spec used here is a hindrance to your raid. DoT every target alive (both drakes as they pass over) and both ground adds. Prioritize drakes over anything else, but always DoT up every possible target. Ignore Sappers; they are not your problem. During Phase 2, keep your DoTs on Warmaster while you DPS Gorianna to 85%. Once she lands, keep UA, Corruption, and Agony on Gorianna and Warmaster. Once Gorianna is gone, simply avoid Shockwaves and finish the big Tauren.
Spine - Demonology
Any other spec used here is a hindrance to your raid. If you are assigned to dealing with Fiery Grip, make sure you have a pre-casted Hand of Guldan queued to hit the Corruption just as it begins the Fiery Grip. Keep Shadowflame on the building number of oozes throughout the entire fight.
During the Burning Tendon phase, you will want to pop Metamorphosis 3-4 seconds before the Tendon is exposed. Also, make sure your Felguard is out. Make sure your Immolation Aura is on, Demon Soul is used. Open up with Curse of Elements unless you have an Unholy DK or Boomkin in your group. Rotation should be:
Curse of Elements > Grimoire of Service > (Felstorm x 2) Doom > Immolate > Corruption > Hand of Guldan > Shadowflame > Touch of Chaos
1st Tendon 1st Burn - Meta, Demon Soul, Service
1st Tendon 2nd Burn - Meta, execute phase
2nd Tendon, 1st Burn - Meta, Potion, Service, Demon Soul
2nd Tendon, 2nd Burn - Meta, execute phase
3rd Tendon, 1st Burn - Meta, Demon Soul, Service, Bloodlust
3rd Tendon, 2nd Burn - Meta, execute
In order to help the tank keep the number of adds in check, feel free to use Hellfire a few times to kill a few of the oozes on the 2nd and 3rd plate. Don't kill too many...each one does physical damage to the whole raid upon dying.
Madness - Affliction
If you felt gimped as a Warlock on Spine, be prepared to take over the meters on Madness. Nothing really changes from normal mode except everything is alive longer and you have the new parasite to deal with. Damage it based on your raid leader's instructions, and keep everything else the same. When Hemorrage happens, begin putting Unstable Affliction on each of them. I hope you have a good graphics card for the amount of yellow numbers you will see at this point. During his Cataclysm cast, Drain Soul will be doing some of the biggest spell hits you've ever seen on your Warlock to date.
When single targetting the Corruptor Tentacles when the Arm or Wing hits 70/40%, apply your DoTs to as many of the tentacles as you can. You're not great here, but that's ok. Repeat this for the 4 platforms.
During Phase 2, you will need to carefully watch your dots so that you don't push Deathwing to a new threshold based on your raid leader's assignments. Putting Deathwing at the 15%, 10%, and 5% marks on demand allows your healers and DPS to prepare for the mechanics at hand. Having a Doom crit tick for 200k can and will cause a wipe if no one is prepared for the bloods (self-taught lesson). Your role here is to DoT the Fragments and Terrors while focusing on the focused Terror. Nothing changes from normal mode in that perspective. Where the fight changes is every time Deathwing loses 5% of his life, he summons Congealing Bloods. If one blood gets to him, it will likely cause a wipe. When DW hits those threshold percentages, look for the forming spots of orange to indicate where these bloods will form. All forms of slows and snares should be used to AoE these down super fast. If they are not snared, they will run towards DW with alarming speed. Hopefully you have a Chillblains Frost DK, Assassination Rogue, Hunter, or other good snaring class to assist you. Your best ability to use on the Congealing Bloods is Rain of Fire. Each specific hit has a chance to proc Spellweave, and it will give you the greatest burst potential. If you are low on life, you can use Harvest Life, but my initial testing shows Rain of Fire far and above Harvest Life.Once called for the burn, execute your Drain Soul set up and enjoy your achievement!
If any of you have specific questions about this raid, feel free to contact me. I have done each fight as each spec and offer insight on every aspect of this raid as a Warlock. Hope this provided help for someone!
