if you can strafe or move your team separately from your main that should cover it for heroics (you may not even really need it if you over gear them). This allows me to keep tanking on my main and move my team independently. I have a 2 keys for left and right strafe that moves my all my slaves but do nothing on my main. This makes it easy to get out of fire / poison / black circles, you know all that good stuff we aren't supposed to stand in.
