Also make sure that you unbind the WASD keys on the slaves. Replacing the keybinding with the arrow keys except for the W which I have bound to a macro that is simply:

/follow focus

You have to make sure to have you're salves set their focus to the master if you want to use that setup. This allows you to still control the slaves in case of a master death, but they never stop following. It doesn't hurt to unbind the auto-run on the slaves as well.
