With that sort of thing, I find myself having to manually reface everyone not facing the thing they're supposed to. There's a good deal of luck involved too. The Tremor Totem is invaluable, but the 5(?) second pulse can go off just before the fear, and then everyone ends up out of range for the next pulse. This does get fixed next patch so that it cleanses fear every 3 seconds, so if you can wait til then, it should become much easier.
