I run a paladin, priest, shaman, mage, and warlock. But the shaman is level 70 and has been PLing the rest of the group as enhancement spec. The rest of the group is currently 55. When they hit 60 I will set the paladin as the main and tank with him, using the others for support.

Since I'm mostly PLing, my macros aren't all that fleshed out yet. I did make one that has the priest and paladin cast their 'big' heal at the same time (with the paladin using Divine Favor first). And I set a pair of keys to use their AE abilities. One key for the paladin (consecration) and warlock (hellfire) since they don't have to spam it, and another key for the mage (arcane explosion) and the priest (holy nova) which I spam after pressing the first key. When I want to AE a group, I pull with the shaman. He places a stoneclaw totem and then a magma totem, and then the lightshow begins! The best part is that holy nova heals the warlock through hellfire.

I'm actually pretty excited about getting to 60 for Outland instances. I expect a lot of early wipes and pain, but it will be a fun learning experience.
