So I specced my 393 warlock into destruction and stepped into my first dungeon as a destro lock and the numbers were more impressive than affliction, let alone the priority based rotation that would punch affliction in the face any day of the week.

I never played destro before as I've been affli/demo since wotlk, but I've seen videos of 60-80k Crits from destro.

How is this possible? The highest number I've seen was 30-35k chaos bold/Conflag. What's up with that??
