Goodness of Monkey Runs - 14M exp per hour x 4

[Korruptor]

Thanks again Mercurio for help with tanking my team of 4 through some of the Monkey runs the other day! I completed my Alliance team through questing the Pandarian story line to 90 after that.

Now with my Horde team I was thinking of using a WoD 90 boosted Death Knight to do Monkey runs with the other three tagging along. I've been gone a while so I'm not familiar with a DK's current state.

Would this be viable in terms of speed of clearing the instances?
My tentative class line up currently is
UD DK
UD Hunter
Orc Shaman Or Mage ?
Orc Shaman ?
