I've played against Empire that drowns because they can't figure out who needs to move where to keep what buff from which unit to ensure a flank charge from which detachment blah blah on and on. Their movement phase was a wreck the whole time. It was enough to make me think maybe the whole detachment/parent unit thing is a waste of time. I'm sure you're capable of keeping things under control in the movement phase, though.
