It certainly makes sense to spend more fp to heal more people for the same amount, on a normally-single-target spell. With the huge fp pools you can get with high WIL and the right setup, I doubt it'd be much of an obstacle for dedicated healers and they're still getting the massive bonus of being able to cast on multiple targets with just 1M more.

I can't comment on the balance much since I stay away from those character types, but I definitely agree that it just seems sensible.
