Speaking of DPS

[Coltimar]

While on the subject of broken macros and how to get your DPS back up to snuff, I wanted to get some thoughts on what I am accomplishing. I have played sporatically of late and I don't really have any one to compare myself to but I am curious if I am doing OK for the gear I'm in or if I'm sucking hind tit on DPS.

I can clear 5 heroics without much trouble (that's all I have really tried) but I see that everyone here seems to pull about 2k dps at a minimum. Here is what I have and what they do:

Coltimar - Colt, my tank, does about 1085 dps in a typical day (these stats were taken during the course of the 4 heroics I did today)
Marlun - Dedicated healer, still pulls in around 600 DPS
Teetoe - 1465 DPS
Jermayne - only pulling 1478 today
Jackea - generally my worst geared toon doing 1702 DPS for the day

Here is the DPS macro I'm using:

#showtooltip
/use 13
/use 14
/cast Elemental Mastery
/castsequence [target=party1target] reset=combat flame shock, lava burst, lightning bolt, lightning bolt, lightning bolt, chain lightning, lightning bolt, lightning bolt

I used to use a series of /castsequence macros but this one does almost identical DPS for me.

Is this low for my gear/spec? Just from reading what everyone else does I think it might be but I am not sure. Always looking to improve.

edit: For totems I drop about one of everything (Strength of Earth, ToWrath, Flametongue)
