Seems a lot either missed the post, or forgot about it. In 1.20 (the patch prior to jobs) the dev team will be moving some abilities around to classes they feel fit better, so we will likely see all the elemental spells moved to thaum, and the astral/umbral stuff moved to whm.
As for the blm doesn't have to have elemental spells like 11, this is silly, it's not 11, it's a FF tradition, the BLM has always had elemental nukes, always.
