3 thoughts. One: Break follow with your pallies attack (like put a movement key for your alts tied to your pally's pull key)
Two: Have a movement for your whole team, your main only and your alts only. For me, WASD is main only, arrow keys are everyone and I use 2 keys from my Logitech G15 G-keys for my alts only.
Three: Stagger follows, have your healer follow your main, and then have your DPS follow your healer. It puts them an extra 5 or so yards back. This is what I did back in the day when hunters had to far away to attack.

You can use Jamba to do the follow after combat so you don't have to worry about it.

Hope that helps and good luck.
