If you hit one mob for 200dmg with Blizz II, you hit them all for roughly same damage depending on the roll of the dice, some might be off +/- .5 to 1%, but that's about it. You are not hitting each mob in the encounter of 10 for 1200 potency each. Also, this is not factoring in any resists, misses or stoneskin effects that any mob at any given time within that pack can reduce that potency.
It is really not a hard concept or equation to understand.
Most of you are misunderstanding the simplistic nature of how DPS is measured across a group of mobs and that it is an accumulative amount of DPS, not multiplicative.
