^ ThisThe problem is, HPS is a stupid metric
Seriously... most people still thinking that healers can stand there and spam heal like no tomorrow so they love to talk about this stupid HPS and such, while healers should already know that in reality, healing is all about situation.
For me, I'm in favored with SS. For example ~490-500, you can cure I,II with speed of 1.85 sec and approximate gcd of 2.35 sec, which help tremendously as you have to move around.
The debate over SS / Det / Crit for secondary stats is pretty ridiculous.
If I really have to choose, I'd say SS till I reach the speed I need then all to the PIE for MP regen.
