First off, I want to point out that this was not a test to compare what rotations should be done, or situationality of abilities, it was purely a dps test for sustained AOE damage from Blizzard 2 compared to sustained damage in a myriad of fire 2 rotations. Discussion about efficiency and optimal rotations really don't apply. The only thing I wanted to bring attention to is that the cost and cast time for fire 2 make it less efficient in most situations. Situations where it should be used it can be foregone for a weaker spell that actually works better and requires less thought to use. I certainly don't know where the debate started about using aoes all the time rather than single target dps, since the entire point of my post was how fire 2 compares to blizzard 2.

The only reason my tests involved 3 targets is because I only know of one location where there are three striking dummies close enough to continuously AOE on.

With several phases in turn 4 and the emergence of wanderer's palace mass pulls aoe damage rotations are increasingly important. And maximizing dps should be a concern. Whether it should be the only concern is again, not a point I was discussing here.
