Not running WMMMP; however, I am running DMWSP, and they can be mana hogs too.

I would typically park them in the spot I marked in the image. My druid tank sits out front, grabs each one as they come. You can drink in-between each boss. A few of the bosses don't hit very hard and allows my team to drink a lot more. Hope that helps.
