There has been alot of very close calls where Benediction just goes off too late and ends up being used on yourself because you targeted a 0hp player.
How do you healers find this? I personally wish benediction doesn't go off when you are targeting a corpse, because it is a very valuable skill that has a 5 min CD.
I'm not sure what the technical limitations are or that is an intended design, which I can live with, but its a quality of life thing and it would be nice, personally if that changed.
