More efficient. Why reach in and remove a tumor when you can change it so that it's impotent? Not that that's necessarily possible, but the same applies to the Sevenfold Covenant. We don't waste energy, time, or risk to do things in the natural way. Instead, we make the unnatural way natural so that--well, the body fixes itself.
