*sneaks in from the shadows*
Hello!
Having been off the scene with my warlock for a while, I am still using the deep destro spec. I know my application is still on pending but am interested in what the best spec is at the moment whether I am accepted or not

Deep Destro has hardly changed (conflag nerfs/buffs notwithstanding) and the playstyle is as it was back in 3.1. It's a competitive and flexible build that's still delivering big, big numbers. It's also fun to play (don't get me started on affliction

).
You're running the 3/14/54 build I see, a solid build for when you're lacking +hit. How long have you had this for? Your gear seems to have passed this now and you'd probably be just as good with a
0/13/58 build (same thing really but with that lovely Replenishment). It's not a huge difference, I just hate that Life Tap glyph with a vengeance and prefer having a steady return of mana

Points are largely interchangeable but this build has served me well.
If you go with that build, remember you'll need about 13% hit (you're at 13.27% at the moment, this is good) with a boomkin/spriest present. Without, you'll need 16% with this build (boohoo).
Glyphs: just change LT for Immolate. Rest are fine.
I hear demonology has some new found dps? Does it now match, or even better destro?
Yes, yes it does but only with ridiculously good gear. I've seen it done very well (rarely) and very ... not so well (a lot). There's no doubt that it's fun, but personally I think it's one for 25-man raids; I just don't see how it'll benefit a 10-man raid scenario properly when you compare it to deep affliction or deep destro. Still, fun > results (most of the time!).
Any advice regarding the current destruction build, whether or not the rotation has changed or been adapted (other than conflag now being a dot)?
Conflag has a DoT component now, rather than being the overpowered nuke that it once was. It's still awesome

Rotation/Priority:
Firstly, are you on Curse of Elements duty? If so, CoE. Then:
Immolate
Curse of Agony if mob won't last 60 seconds | Curse of Doom if it will (ignore curses on packs of trash, just AoE)
Conflagrate
Chaos Bolt
Incinerate <-- this is your "filler" spell. Use it when all the others are up or on cooldown.
(Only use Corruption when you've got to move from A to B, or when you know that you won't be able to DPS a target for a few seconds.)
Comments:
Immolate has the biggest bearing on your DPS so keep it up at all times. There's no set-in-stone rotation so it's kinda flexible without being too confusing to make give you braincry. Try using addons such as DoTimer or ButtonTimers to help you manage your cooldowns, I prefer the latter.
And finally, How do we all feel about the warlock pvp specs?
I run away!
No, in all seriuosness I haven't a clue. Destro works well in Wintergrasp and the like because of its high burst damage and high mobility; Demo may lack the "oomph" but will certainly give you more survivabilty.
Pro PvP tip: don't let people see you. We're awesome when they're looking the other way.
AfflictionI'll dig up an Affliction write-up for you from our forum when I've cleaned it up a bit. In short, it's theoretically higher (ZOMG BIG NUMBAHS!!!1!) and in sustained-DPS fights it's a clear winner. I just don't like it. It's too hard for your DPS to drop off in a high-movement fight (such as any in ICC).
If you want any tips, collar me in-game and I'll be happy to help. I'll probably be on Flowette, Kerviel or Madoff

Good luck!
