If you could build a class out of all of your favorite specs, what would your perfect class be?

I was trying to decide whether I'd rather play my Monk or DK in the upcoming expansion and I kept coming down to wanting the Tanking from a Blood DK and the dps from Windwalker. After thinking about it some more, I think I would round out my class with something between Elemental Shaman, Frost Mage, or Unholy DK. Maybe Mistweaver or Resto Druid if I got to pick a 4th spec.

What specs would you guys weld together into your amalgamation of mechanical perfection?
