One of the first things I would change about consular class I would remove the shadow class from it. The shadow class just does not fit the consular. Lore wise the shadow is a sub class of the sentinel. I am not sure why the original devs put the shadow with the consular. Maybe there was not enough time or money to create three force user stories.
That said, the consular should have been a healer and range damage. Jedi sage and Jedi healer (Jedi seer) to be more exact. Or if they wanted three skill trees then they could have gone with a Jedi sage, Jedi mystic ( range damage and healing), and Jedi healer or Seer. In one sense, this class should have be similar to the WOW priest.
