I agree regarding WHM. While the lore and quests are heavily focused on keeping harmony with the elementals and the Twelveswood, if you look through the ability list, most I would say are unthemed (Cure, Medica, Regen, Presence of Mind) or have an ecclesiastical theme (Holy, Benediction, Assize, Tetragrammaton, Divine Benison, Plenary Indulgence). You could maybe say Stone & Aero are nature-based, but they're also just simple offensive expressions of the earth and wind elements. Even the AF set names (Healer's, Cleric's, Orison, Seventh Heaven) imply the job is more of a cleric than a druid.

If they ever figure out a way to make Geomancer a full job rather than how it's presented in the AST quests as "the other side of the same coin as AST", then I imagine that might give you what you want.
