I agree Heroic mode parses are preferable. In addition to having the higher skilled pool of players it shows you how the spec performs under more complicated fight mechanics. If a spec has a larger dropoff in performance in Heroic mode then the spec is more likely to get sat. In Normal you just have to perform the mechanics correctly, you don't have to also put out high levels of DPS at the same time. However since most players are in Normal mode right now I think it is worthwhile to look at, especially since this is the first look at how specs are performing in this expansion.
