Well, I wanted to give my two cents, but it ended up being way too long, so I've posted it separately here:

That one however uses the full elemental spell wheel for BLM/CNJ, and more soul-related / Astral-Umbral magics for Thaumaturges, as was originally the case. This is probably just because I don't especially care one way or the other as to who would be the dominant healing class pre-job, that both should have access to WHM and BLM, using previous spells + job specifics. First and foremost I want them to maintain their own themes, a Conjurer *conjuring* defenses and elements, while Thaumaturges magics lie in a more abstract Light/Dark style. As long as each fulfills the roll in a different and self-fitting manner, I couldn't care less that they can share role.
