Definately do not level Vitalism unless you are going Paladin or Ranger.

paladin is Vit, Battlerage, Defense

Ranger is Vit, Archery, Shadowplay.

If end game healing is really what you want to shoot for then you are going to want:

Templar vit/def/auramancy

Cleric vit/songcraft/auramancy

hierophant vit/aura/witchcraft

Keep in mind that every build combination has both offensive and defensive capabilities depnding on your skill choice so there are tons of options for leveling.
