Your post doesn't provide the one piece of information that might actually enable someone to help you - a log of an actual raid. Without that, I can sum up your post as: "Please help guys! I'm trying REALLY HARD but I still suck!"
That's not news.
Original Post:
I have read and tried all sorts of rotations and for whatever reason I cannot get my dps up or at least not constant. Yesterday I finished gemming my new gear and I still got the same results as I did with the conquest set. Anyway I was able to hit 4.5k and averaged around 4.0k for my first go. I was happy all and all. But everytime after that I was lucky to maintain 3.5k and really even 3.0k. And that was on the dummy in orgrimmar. Regular and heroic dungeions and even the 25 man VoA I got in and the 10 man ToC I couldn't even hit 3k. At least not withou a crit.
All this is a little embarassing when, while I know it doesn't mean that much, I have a 5391 gs, 2300+ sp, over hit cap with one set of hands and 10 or so under with the others and around 700 haste, 20%+ crit and all that.
I am affliction spec and have rebuilt countless times and really tried everything I can find and think of.
Current rotation is UA, corruption, haunt, CoA (CoElements at times for longer fights), shadowbolt spam until I need to reapply UA or Haunt. I have read to not reapply until they are down and off and even to not let them drop. Reupping them in time to not lose ticks. And still no luck. Any suggestions?
