We'll consider it when you've tested it and have some data to show.
I'm actually interested in the change to Shadow Dance: Shadow Dance cool down reduced to 1 minute.
Before you write this off as nonsense, try to at least consider it. Now Shadow Dance has an shorter cool down that Killing Spree w/ glyph.
Me and my friend fooled around with a few specs in the calculators; it looks interesting and maybe worth a try (though we have serious doubts about it since it requires a dagger MH for Ambush). If anyone is interested in diving further, I created a spec using mmo-champion's calculator... possibly not optimal... possibly so... but Blizzard continually improves Shadow Dance with every patch. Maybe it might be worth a look at?
We left out Precision as it might not be needed in T9, added Vigor for better burst during Shadow Dance. Not saying that anything in here is how it should be... just giving the reason behind some of the more questionable parts of this spec.
