I'm with you V. I can go a few days without playing, but when I do I want to stay up all night and clear Naxx25 in one go.
I was under the impression that the content-clearing guilds all spec'd a Destro or Demo/Destro hybrid due to the debuff limit and consistent output. Affliction = spikey if you don't have the rotation down.
But that was just an observation, and not a fact.
