Best class to compliment my friend's hunter?

[:1]First WoW character (if you can believe it). Have played UO, EQ, AC, Matrix Online, Aion and Rift though.

I usually stay with Hybrid classes but have gone Ranger or Mage lately.

My friend wants a pocket healer of course, but I don't want to be just healing all the time if you know what I mean.

Any builds and strategies are welcomed. I do use hardware and software macros on my mouse to keep from having to button mash so long chains aren't a problem.

Thanks from a WoW noob ;)

Edit: Leaning towards Shaman or Paladin (suggestions? gear/rotations?)|||I'd suggest Shaman as well.

Enhancement / BM hunter blow things up quite fast, but when I played along with a friend's hunter I found it was a bit frustrating to play Melee. Shaman have the option of going Caster DPS as well as Healer. Dual DPS is fine for pretty much anything you'll encounter outside of instances and you can always go Resto if needed.|||thanks........
