If your raffing the dpsers, go shammys and make mages too.

Im now levelling my shammys, got bored with the mages, and good part is you can mix the teams up too, mage or 2, shammy etc.

My other set is mage, boomie, hunter and priest healer. I dont tank, my fiance does that while I use the other 4 toons.

Sometimes I add in a mage or 2, or at times use all 5 mages, depends what I am doing,mount farming etc I use mages + my main hunter too leech the mounts if/when they drop.

Shammys are handy if 1 dies, it can reincarnate as well. And if you need extra boost heals all chain heal and so on.

Level a few sets if your raffed everyone here always recommends doing it and its truely worth while down the track.

Also look at the macros and 2 step macro as well, awesome for mixed classes in your team for easy dps
