If you speed up breeding with gems, then the sanctuary means little to you. If you let the breeding process take its natural course, then the sanctuary is wonderful. That upgrade shaves 20% off ordinary breeding time. It does not decrease or increase your chance of getting rare dragons, at least that's what the wizards claim.
