SCH is an awesome healing class I don't know why ppl complain about it -_-, they just don't understand how SCH is played WHM is supposed to be a powerful pure healer but SCH has so many different tools at its disposal as a healer and is IMO the best tank healer in the game its its all about being Proactive instead of Reactive!! ive easily out healed WHM on titan (not a bad thing BTW) due to just mitigating so much damage that the the WHM doesn't have to shell out so many heals to cover raid that they run out of mana giving them time to worry about that "OH SHIT" moment, WHM and SCH are the perfect tag team we allow each other to shine at our maximum ability while taking the stress of our weaknesses off of each other (WHM lack of high mana pool, SCH lack of AOE spike heals)

there's no reason to boost SCH or to even compare it to WHM neither is the better they are both a necessary part of a good raid group.
