This is a good point. Two WHMs together are usually pumping out ridiculous overheal, and their DPS is not nearly as sustainable as that of the SCH.

Given the choice, I'd pretty much always take 1 SCH + 1 WHM for end-game content where 2 healers are desired.

For casual content, as I said before, it doesn't matter at all. Slop shields all over the place or blow your party up with HoT spam, because it makes no difference when the challenge level is low and the players are extremely overgeared. Two of the same healer isn't unworkable in most situations, just not optimal.
