I'll ask again. Why should a healer move into Cleric Stance in order to DPS in a dungeon instance? (We know the answer to that in the MSQ: "So we can complete the story line, duh."

We already know healer DPS is not considered from a dungeon design point-of-view.

I suspect that a few healers would even be encouraged to cast DPS if they don't have to worry about being called out for "not being in Cleric Stance".
