I had a talk with the devs about this very issue yesterday, and they are well aware of this subject, and tend to agree with those of us (one of my mains is a holy priest) who have noticed that Sanctuary could do with a buff.

There are two things that have to be dealt with here: 1) Holy priest AE healing is pretty decent as-is, and 2) we don’t want Sanctuary to be so similar to Healing Rain.

Again, the devs agree that a modest buff is a fair solution, although it is hard to know when or by what magnitude such a buff might come along.
