Forged Alliance

I wanted to start us up a thread to talk about how many tanks/healers, etc we need for gruul's.  Anyone with experience there please let us know what you think.  Just from reading up, I know we need a mage tank, and I believe Mike (Another) was volunteered for this position.  It would probably be good to have 2 mages geared up for this in case one can't make it.  I know it involved a lot of stam and +spell hit.
