I'm going to try and attempt to summarize the vast wealth of information going around.
Warlocks have many great talents, and there is lots of wiggle room. Consequently, there are many viable hybrid builds. To keep this rough guide short, I'll focus on the three main tiers.
[Warlock] How do you do dps - affliction style - Unstable Affliction (41/0/20)
Affliction is all about dots. Typical demon choice for this style is imp.
Even though your crit chance is lower than destro, you'll want to have improved shadow bolt in most situations.
How to play:
- You never want to lose a single tic of unstable mutation, corruption or agony. When all your dots are up you will be using that time to throw Shadow Bolts or Dark Pact/Life tap.
- You probably want to use an addon like dotimer. Since your dots are your strong side, making sure they're all up is top priority. There is no fixed rotation since your dots are on
- Malediction is beneficial, adding 2.7% shadow damage to the raid over the untalented CoS.
- Get your imp buffed, blessing of wisdom helps a lot for his mana regeneration, which you can siphon off with dark pact.
Strong and weak points
- More mana efficient and self sufficient than other trees.
- Bloodpact can be nice to boost hit points, especially on fights where a tank can get flattened fast, or where there is lots of aoe damage on the raid.
- Ideal in situations when two or more mobs are being tanked, as you can dot them all.
- This spec provides less burst damage, and scales worse with gear than other specs.
How to gear
Spell hit > Spell damage > Spell haste & Crit
Most warlocks use Suppresion to reach the hit cap, and spec out of it when they obtain more +hit on their gear.
[Warlock] How do you do dps - demonology - Felguard (0/41/20)
Demonology in raids is about making best use of your top tier Demonology talents. The strength of these can make up for the lackluster mid tier Demonology ones.
Demonologists get a boost to spell power, get a 5% damage bonus due to soul link, and get +5% to crit with spells. It is vital their pet stays alive, though. A Demonologist without a pet is very ineffective.
How to play:
- Key is to keep your Felguard alive. Micro managing your pet is vital, since him dying means losing a lot of dps.
- Spell rotations are similar to affliction, with a higher accent on (improved) Shadow Bolts.
- Remember to have your pet attack from the back. Melee attacks from the front can be parried, which can cause an instant counterattack.
- Ask for buffs on your pet. His stamina and intellect will boost your attack power, and it'll allow him to stay alive longer.
Strong and weak points
- Demonology relies on having the Felguard out, so the effectiveness varies a lot. Some fights are brutal towards pets. Micromanaging your felguard is vital.
- A very versatile spec due to the demons each having different effects on you.
- Can be used to offtank in specific encounters (Leotheras being a prime example)
- Demonology is probably the least gear dependent of all three specs. Exception is the tier 5 set bonus heals your pet for massive amounts. Before obtaining that, demonology is likely to perform less well than the alternatives due to the extra healing required on the pet. Shadow Priests in your group will obviously help a lot.
How to gear
Spell hit > Spell Haste > Spell damage > Spell Crit
Tier 5 two part bonus is very useful for this spec.
[Warlock] How do you do dps - raid build destruction - Shadow and Flame (0/21/40)
Shadowfury is a really nifty talent, but it doesn't shine in raids. It's usable in specific encounters and very good in those. But its use is rather limited in raids in general. That's why most people default to using 0/21/40, taking a few subpar talents to obtain Demonic Sacrifice, which boost shadow damage by 15%. I'll focus on that one here.
This build focuses primarily on Shadow Bolts with a high crit rate. At low gear levels, fire spells are viable, but they scale worse compared to their shadow counterparts. The key thing is to keep the Improved Shadow Bolt Debuff (ISB) up as much as possible, since it provides 20% extra shadow damage to the entire raid (including dots - this is a common misconception).
This spec scales best with gear, due to the high return of spelldamage and crits on Shadow Bolts. There has been some debate about what gear is needed for it to outperform affliction, and opinions are divided.
How to play:
- Sacrifice Succubus. Spam Shadow Bolts. Life Tap when needed. Bring potions, healthstones and bandages.
- Curse wise, if you don't have to provide recklessness, CoS, CoE or CoR to the raid, Curse of Doom or Agony are good choices, provided you don't lose tics on them.
- Corruption is marginally better than shadow bolts, usually, provided it doesn't get knocked off. If you lose even a single tic, or have to move to be able to cast it, Shadow Bolt will be superior.
Strong and weak points
- This spec has the most powerful burst damage. This is a boon when things need to die quick, but it makes it harder to manage threat while still maximizing dps.
- The least resilient and mana effective spec, requiring the occasional heal to be able to dps. With the exception of Bosses using Shadow and Fire spells, since this spec can come with Nether Protection.
- Scales the best with gear, due to Shadow Bolts getting a 104% bonus per +damage (3/3.5 + 0.2 from talents), more dps than any other spec.
- ISB uptime is hard to measure or model, but provides a boost in shadow damage to the entire raid
- This spec requires a lot less management since there are no real dots to keep track of, and no pet that can die. Some warlock dislike the lack of variety in spells used, others prefer it because it allows them to focus on other things, like keeping an overview of what is happening.
How to gear
Spell hit > Spell Haste > Spell damage/Crit
General gearing issues:
There are 4 main statistics for a warlock for dps:
Spell damage
Spell hit
Spell haste rating
Spell crit
Each of these has diminishing returns. If you have large quantities of one stat over the others, you can probably improve by making tradeoffs.
Spell hit is a special case, because it provides the most effective way to increase dps on bosses and is useless on everything else beyond 5%. Typically Warlocks will use two sets of gear, one for bosses and another for trash mobs or add fights.
Spell haste rating largely depends on the spells you use. Destruction warlocks will favor it most.
Tools for measuring DPS would include:
SWStats (or any other synching damage meter)
The other warlock dps spreadsheet
ShadowSeer Beta (which I'm shamelessly plugging here)
