They're instant, free (or marginally priced), and allow the user to continue uninterrupted. Healing-wise, the more powerful part of SCH's kit is the "good" half, and the more powerful part of WHM's kit is the "bad" half, i.e. the less efficient heals you want to rely on last.
Agreed. To add onto that the oGCD healing allows for higher DPS. Which explains why WHM wins on the target dummy parser, but loses to everyone in actual boss fights. Those lost DPS spells spent on healing GCD, just can't compete with being able to weave DPS into your heals.
