Naah..sorry guys. Not a noob here. When I'm demo I max out mastery, have macros set up to use all trinks, demon soul, etc when needed, switch out one trink to MWC, switch pets when needed, pre-pot, get out DG when all procs are out (most of the time). Believe me, my gear is forged/chanted as it should be as is my rotation barring any RNG.
As far as destro, I take off MWC, put back on Insignia, reforge everything out of mastery to haste/crit as the case may be.
Should also mention this isn't a once or twice thing. This is three weeks! Guild is now trying heroics but 25s are a bitch and we've only gotten H Malrok (sp?) down twice...wasn't there either time too..bugger :P
You guys are pretty much saying the same thing I am..I should NOT be doing better damage as destro. I agree. Not working out that way though.
I will say one thing though, my rotation for destro is now on par with demo. Think I like it better
