Looks very similar to mine.

I use
CoE
Immolate
Conflag
Chaos
Inncinerate


The very first thing in my macro is this though:

/castsequence reset=combat ,,,,,,,,,,,,,,,,,,,,,,,,,(almost 255 maxed),,,,,,,,,,,,,life tap

Its an emergency life tap if I forget to monitor it... if the warlock runs outa mana, it'll life tap and keep her going.

Is your Imp on passive? If he's not attacking, its going to screw up your DPS. And armor? are you putting armor on? (the right one?).

Something I noticed too .. at 78, Destro and Afflication (post 3.3) are very similar in DPS - so I'm wondering which one is going to take off with the gear.

EDIT:

Seriously dude? You're bitching about almost 7000 DPS?
