I don't have my movement keys bound to the same ones on my followers. I move with EADF (my FPS move/strafe keys) and the followers use the arrow keys. Normally they just /follow me and /assist me. There's some tradeoff for keys, as you don't want all keys being used all the time for the same actions. The subtleties are constantly being discussed, and a lot will depend on how you like your setups to work.
