Scholar and Whitemage are currently very balanced, and compliment each other awesomely. (Probably one of my greatest praises of XIV; balance')

Both Seline and Eos can easily solo heal the current HM's while you DPS full time (SR you can partially DPS) if i90.

TBH....if you don't want to micro-manage a lot.... play WHM, quit healing in XIV, or quit XIV.
