I've played enhance since Sunwell and before this played as resto since vanilla. I have never run into damage problems and even in TOC/TOGC I was always in the top 5 dps for our guild. Fast forward to ICC when I finally get enough frost badges to get the trinket and I change out all of my gems to haste. Reason I did this is becuase it simmed for much higher dps than my AP gems did. Since then, even though I've upgraded almost all of my gear, my damage is pretty low. I know sims are just a tool and represent your potential more than your actual performance. But my gear is simming out to about 9800 and on miminal movement fights, I'm hitting about 8600.
I use S&A, always have, so I don't think it's a rotation thing. The one thing I'm thinking is that since I've switched from AP to Haste my dps isn't the same. I'm thinking that since I've gone from about 200ish haste pre-ICC raids to about 700 haste now (even more with procs) I think with the tighter rotation I'm just not able to keep up.
I realize I'm not giving all the variables here to properly diagnose my issue but I've always been able to fix any dps issues in the past and I'm wondering if switching back to full AP or even haste/ap gems could possibly help. Rawr shows a dps loss but I'm wondering if actually game play would show otherwise because of my seemingly slower reaction time.
