Firstly I'm a mediocre healer mostly dungeons for FC and friends. I Never got the hang of SCH there was always just to much for me to think about, Even with all the changes It's still to much(deployment tactics, aether management, fairies) Not criticizing just explaining why SCH has never suited me.

I fell in love with AST using it for PVP and mostly played that through out the last expansion. However From what I have been reading it seems as though their healing has taken a hit? The new card changes are humdrum but it's not like anyone I ever healed for even noticed a bole on them anyway :P . I did doze off the other night doing fates but I think that might be a common problem with healers in 5.0

Then there is WHM which has always seemed like a straightforward press the button and heal job to me. Not overly complex not overly simple.

I want to heal and be comfy and be able to handle a crazy tank pulling wall to wall with out pulling my hair out.
