is my guess on an unholy dps build for cataclysm, the day the NDA on the cata info was lifted.

Im almost certain the frost subspec will look real, real close to that. 3/5 Runic Empowerment could be 2/2 Icy Reach. And Icy Talons i'm real unsure about, but I expect it to be addressed in the glyphs. Icy Touch to reduce attack speed, now that the talents no longer address it?

I don't like that the glyphs aren't showing at the moment, but I would guess icy touch/scourge strike/the ghoul will be standard. Scourge Strike, at the moment, isn't relevant. But my best guess is it will be come 4.0
