I'm in the minority where I didn't see Dancer working as a healer in XIV, it worked in XI because XI actually supported the idea of true support classes. It makes more sense as a DPS in XIV, what would have been nice as a new healer for healer mains is something similar to Chemist or Geomancer, but god knows they'll make the excuse that we already have Alchemist as a crafter and Geomancer is already mentioned and has a part in the AST storyline.
