This is true but medica 2 does almost as good a job. I can't see cure 3 being better than medica 2 unless a boss is doing his party damage nuke attack more than once per 10 seconds. Even if you managed to get everyone stacked up in one place for cure 3 to hit all targets, Medica 2 already out healed cure 3 within 2 ticks of the heal over time.
