I double box with my main as a feral druid, so the hunter just finds a spot, I execute a macro for mark/pet-attack/auto-attack, and then I have the various hunter skills timed with autohotkey. The only thing is that I wish that I were using a mage or even better a warlock because then I can just put them on auto-follow while my druid tanks and they can just blast away. Since the hunter issue starts at 8 yards, he has to park somewhere. My workaround for this is to have a specific key bound to follow the druid and another key to stop following. It works very well for me.

Come to think of it, I wonder if the best duo combination for a feral druid would be a shadow priest since threat doesn't matter...

Edit: Another note: I'm not sure how this works, but I noticed that when I execute my pet-attack/auto-attack macro that the hunter turns to face the target. I'm not sure how...
