Well, I'm a warlock that really wants to see over 2k dps constantly in any huge dps fights. I checked out my dps on Rage today and I was doing around 2000-2100 in the beginning of the fight, but towards the end of the middle at around 50% of rage's hp, it dropped to nearly 1850 then back up to 1930 at the end of the fight.
My stats are unbuffed:
About 1250 sd w/ fel armour
233 hit
172 haste
and about 22 crit (27% crit with devastation)
A lot of warlocks that are in end game content that I know tell me to get my crit to 25% without devastation no matter what and that i'll see the constant 2k dps constantly, but they also tell me that my sd is a bit low.
What to improve or dps rotation to hit 2k constantly? I'm usually the CoD lock.

help! lol
