This indicator wouldn't be as helpful for actions that work on a radius like Medica, since multiple targets can often be in view (yes I know my DPS is right next to me, but is the tank in range?). A number showing how many targets will be affected would be slightly more useful, but in the interest of reducing clutter I am fine if this doesn't happen.

I apologize if this suggestion has been suggested before; I did not find any similar threads in a forum search for "cure target self" and similar terms.
