My hunter is level 70 and aside from the Ogri’la questline (kill that big elite, now kill that one, now kill that one), I haven’t played her in groups at all. Big Bear Butt Blogger: Plotting my hunter group tactics has a nice writeup of some macros he plans to use. They seem pretty good to me, so I’ll make note of them in case I need to group some day.

Edit: He’s updated them with corrected versions.
