Need help with Destro Warlock macro

[Smokar]

So my team consists of:

Death Knight, blood tank
Warlock, destro (for replenishment)
Mage, arcane
Shaman, elemental
Priest, holy

It works great and I love it. Everything is going pretty smooth with one exception. My warlock's dps macro is pulling much lower dps than what I can do with him solo.

For example right now in UK recount is showing:
Mage 2874
Shaman 2397
Warlock 1541
DK 1439

I can't seem to come up with a macro for my warlock that pulls better dps and does not get hung up on conflagrate.

Here's what I'm using:
#showtooltip
/assist Smokar
/castsequence [nochanneling] reset=target/combat Curse of the Elements, Immolate, Incinerate, Incinerate, Life Tap, Incinerate, Incinerate, Incinerate

edit - also i forgot to mention, I'm perfectly willing to drop replenishment and respec him to afflic or demo if that means better dps. I've avoided affliction because on short lived trash it really doesn't have time to ramp up. I'll be looking into a demo spec and macros and see if that helps


Also kind of off topic. Here are the macros for my other characters if anyone wants to use them. They work pretty well for me.

Shaman:
#showtooltip
/assist Smokar
/castsequence [nochanneling] reset=10 Flame Shock, Lava Burst, Chain Lightning, Lightning Bolt, Lightning Bolt

Mage:
arcane
#showtooltip
/assist Smokar
/castsequence [nochanneling] reset=combat Arcane Blast, Arcane Blast, Arcane Blast, Arcane Missiles

fire
#showtooltip
/assist Smokar
/castsequence [nochanneling] reset=target/combat Scorch, Living Bomb, Fireball, Fireball, Fireball, Fireball, Living Bomb, Fireball, Fireball, Fireball, Fireball, Fireball

Death Knight:

#showtooltip
