actually druids are refereed to as having faith many times around in pathfinder so i would say the divine label fits well
i think it all boils down to that 4 essence system they added (Material, Mental , Vital , Spiritual) it is specially problematic for the wizard because previously the wizard was kind of a jack of all trades in terms of magic kind of like the bard now
i feel like the arcane schools are now
arcane (Abjuration, Divination)
Occult (Enchantment, Illusion)
divine (Necromancy, Conjuration)
primal (Transmutation, Evocation)
of cource that is very rough but to some degree its true
a 1e wizard would be more of a multi tradition caster in 2e
