Tank and Heal

[Cephalobeard]

Hey, everyone. I've been running a WAR/Shaman combo with me tanking and healing the whole time. This has been fairly effective, but my healer always ends up assisting and running in to combat with me, or even sometimes just sprinting away from combat and into other packs if the mob is moving when I hit an keybind they share.

Any tips on:

1.) Not having my healer in combat with me, in melee range

2.) Not having it run off like an idiot

3.) Anything related to a dualbox of both tank and healer

Would all be greatly appreciated!

Also, I use ISBoxer.
