I tried that for a (very short) while and didn't have much luck with it. Part of my problem was I am so used to using the mouse to turn, my characters were always getting 'out of sync'. It was MUCH easier to just have my second character be the follower.

This weekend I'm planning on messing around with my n52 controller configuration to add different movement key bindings to the different shift levels so I can move one or both of my characters at the same time. I'm running a warlock and a hunter, and when my warlock crits and pulls aggro off the pets, I need a better way to move my hunter back to range.
