However, now that we're pushing heroic content, soon to be 6/12 HM working on the double dragons, I can't justify focusing on demo for progression since we have plenty of raid buffs. Therefore, I have to loose all the mastery I was stacking.
I do my best to get to 25% raid buffed haste for additional corruption ticks on affliction, and then I regem and reenchant my gear to get my mastery as high a plateau as I possibly can for those aoe fights as required for demo. Again, this is probably not necessary for farm content, but it fulfills my OCD nature to be as min/maxed as possible.
You'll do fine to focus your gear toward affliction, and make slight adjustments for demo. You cannot gear for demo and be successful at affliction. If you want/need to be full time demo, you have to unapologetically go all in for mastery.
