This is just a simple guide helping out the fresh 80's (and rerolls) with getting prepared for raiding as affliction in WotLK. I hope it answers many questions and helps improve some players. Questions are encouraged and if you see something that might be a little off, please let me know.
General Information
Warlocks these days give off the vibe of "Omg we're a broken class, fix our dps now" etc.. That's a misconception. Warlocks are a very complicated class and requires precise timing when it comes to throwing up DoTs. The margin of DPS between a good warlock and a decent warlock these days is quite high. An experienced affliction raider can easily toss up 2k dps in a raid whereas someone who's just starting to raid as affliction is going to have trouble keeping up 15-1600 dps.
The generic Affliction spec is 56/0/15 with the key talents being Siphon Life, Haunt, ISB, and Ruin.
Found here: http://www.wowhead.com/?talent=IfxMbzMAoqA0IstZE00V
A few notes on this spec
- No points in Dark Pact - This is because of the scaling with spirit on Life Tap (300%), and the abundance of spirit on our gear, we really don't need Dark Pact, or the full 2 points in Improved Felhunter. The 1 point in Imp Felhunter is a filler point and can be tossed into anything as you please. Personally I put it into Improved Healthstone.
- Soul Siphon - Filler for our dps once our target reaches 25% is Drain Life, works hand in hand with Death's Embrace. Extra 20% damage (if you're the only affliction lock in the group) can not be passed.
- Ruin - Filler spell until 25% is shadow bolt, so you definately want the extra crit damage.
- ISB - Also great with helping out our shadow bolts damage, also works with the initial hit from Haunt.
Also to note, the new hit cap is 367 with supression, 446 without. Blizzard removed the 99% hit cap in 3.0 so now once you're capped, your spells will always hit. Also to note that 1% hit =26.23199272 hit rating.
Spell Rotation Etc
We'll start with the basic DoT rotation for lock.
Shadow Bolt -> Haunt -> Immolate -> Unstable Affliction -> Corruption -> Curse of Agony -> Siphon Life
Immolate before UA due to Haunt having a missile effect so you wanna give it time for it to hit and get the extra stack of Shadow Embrace.
A few simple rules to follow when raiding affliction.
1 - Always start off with Shadow Bolt, then haunt. This allows Shadow Embrace to stack twice for maximum DPS from the get go. If you're on CoE duty, cast CoE then Shadow Bolt and continue.
2 - Immolate and UA are always cast together due to their cast times being identicle unless you have the glyph for improved UA.
3 - NEVER EVER STOP A CAST. Even if you're gonna refresh a dot that doesn't need to be refreshed, you're wasting time and dps by stopping something midcast.
4 - Try your best not to clip a DoT. This means timing it as close to 0 as possible to get the full effect from your dot. This goes double for Curse of Agony since it's damage goes up each tick.
5 - At the moment, Curse of Doom does not benefit from Shadow Mastery, Haunt, or Shadow Embrace, so never replace Curse of Agony with Doom.

FAQ
Q: Isn't glyph of Unstable Affliction useless because the global cooldown is 1.5 seconds and the base cast time is also 1.5 seconds, so using it will just give you .2 seconds of nothing after an unstable affliction cast. Unless it also reduces the global cooldown?
A: This makes boss fights where standing still = death much easier to manage our dots. You can replace this with Glyph of Curse of Agony if you find you're doing fine without it.
Still a work in progress. I'll do my best to answer questions and fix any errors if you find any.
