The Elemental Initiate level 6 utility swap would be amazing... if it wasn't a standard action and melee 1. While as an Order Adept (and trained in Heal) you can grab Herbal Healing from Wizard 2, for a minor action second wind + saving throw as an encounter power. If you aren't trained in heal, Guardian Blades, or Mystical Debris + Terrain Advantage for your CA feat are good runner's up.
