Necromancer: Won't happen for lore reasons. Basically, raising the dead is blasphemy and unholy. Practitioners are seen as evil and are either executed or jailed. That comes from Koji directly in an old Live Letter (that I'm not even going to attempt to dig up, it's that old).
Aether/Bloodmancer: Aether itself is horribly unstable and unpredictable and directly channeling it is detrimental being ultimately lethal to the user. This is why Matoya chastises Y'stola for using it to see since it will slowly kill her. I think Blood magic falls under the same category as Necromancy.
Geomancer and Dancer: We'll likely see these jobs at some point.
