This week's TotW is a quick and easy way to further manage your Fear targeting. For situations where you need to stay on your current target, Focus-cast another, and still be able to Fear on-the-fly, this macro will allow you to Fear opponents simply by mousing over them. No sloppy targeting or Focusing issues need apply here. Just point, and Fear.
/cast [target=mouseover, harm] Fear
Happy mouse-overing. ;)
