I'm seeing a lot of people say things similar to this and I'd like to address it directly. I don't mean this aimed at any one person and I don't mean to condescend, all that aside...
To effectively use Cure III you need to precast. It isn't the fault of your parties spreading out after an attack, they are under no obligation to stay standing there to recieve a heal, either you precast a Cure III (mp efficent if you can make use of the full heal) or if you can't be bothered to precast then you do a less effiecent heal like a double Medica or Medica II.
I just don't like to see these "but my party doesn't stay still long enough" things, it makes it sound like your parties should be compromising their dps so that you can use another part of your kit and that isn't the case. Precast it to land after the attack and no one has to adjust anything at all and you get to use a great skill.
