Poetry, nice spec, should be good for raiding as well since you'll want the imp out anyways for the stam buff. A good imp is a Destro Lock's best friend.

Just a couple comments to think about.

The Suppression talent is pretty huge in the Affliction tree for the +3% hit if you aren't hit capped for the content you are doing (+6% for heroics, +9-10% for raiding assuming good class diversity in the raid). People just starting 80 content may want to have it until their gear makes it obsolete. You could sacrifice points here and there, [s]like the 2/3 in Demonic Embrace from Demonology, to throw over there which would hardly be noticed[/s] (Edit: Doh, just noticed that was needed for the Demonic Aegis talent).

Also, the Improved Shadow Bolt talent in the Destruction tree for the +5% crit buff (technically debuff to target, I guess) can be just as huge for those people that don't often run with others classes that would apply +crit bonuses, like shaman Totem of Wrath (which is only +3% crit however). If you read the talent carefully, it doesn't limit the crit to only the caster. This one is just as situational, though.


Late Edit:

My warlock was a bit dusty when I pulled him out. His rotation was still built on the principle that Conflagrate was best used with less than 5 seconds on Immolate for maximum damage, which is recently no longer necessary. The only difference really from Poetry's rotation was that I had a Shadow Bolt (talented) at the start for the crit bonus, and used a higher rank of Life Tap (glyphed Incinerate instead of Life Tap). And, unfortunately, I guess I overwrote the Affliction rotation with the new Destruction rotation. Wish I had saved that in case I ever went back.
