Pally tank with 4 ele shammy is easy.

I put the shammies in the far corner from the boss and drop totems. After starting the fight I consecrate and build aggro for a few seconds before popping fire elementals. He goes down nice and easy this way and I don't wish to waste any of the summons so I wait for the CD between kills. I'm sure there are better strats but I like simple and I have plenty to do between kills to keep me busy.
