Did I ever say that every boss is a patchwerk fight? It's a benchmark to assess from, not a be all answer. There's two types of people in regards to how simcraft is used, those that think that simcraft sucks or is amazing and those that understand that it has its uses and limitations. It provides a simple framework, nothing more.
I assumed that was the average between the two stat weights for CoP and AS, but when I averaged the two, I ended up with:
CoP/AS averaged stats
Int = 1.0000
Spell Power = 0.88165
Crit = 0.678
Haste = 0.6133
Mastery = 0.44645
Multistrike = 0.56575
Versatility = 0.483
DPS (Pure Damage) = 0.15865
