I leveled all three healers to 60, and Scholar was by far the easiest at all level ranges simply because Eos could simply solo heal by herself while I parked myself in Cleric Stance for 90% of the dungeon. Sounds like some people in this thread never figured out how to use Rouse or Whispering Dawn.

Either way, I agree that both jobs need to be completely split from each other, but for entirely different reasons. The way I currently feel, the Arcanist class was created with Scholar being the focus, with Summoner being tacked on later. A split opens up room for Summoner to behave closer to being an actual Summoner, instead of an awkward poison-debuffing class with pets. I've even drafted up a proposal of how Summoner could get overhauled if this were to happen, though be aware I don't actually play Summoner.
