Level a healer or wait for astrologist?

I'd probably say go with SCH if you're uncomfortable with the idea of reactive healing or WHM if preventative healing isn't your forte. Depends on your playstyle really.

It's a slightly nitpicky point, but I'd suggest that all healers be trained to think in terms of being "preventative" or proactive. Too many WHMs seem to think that reactive means literally waiting for HP to plummet before starting to do anything, and it makes them slow and scary healers. Also contributes to this common mindset of "omg I can't DPS, because someone's gonna die!" :P
