I just thought of one that's not on the list, but I'm not sure if it'll come up, Favored Soul.
Favored Soul in 5E is a Sorcerer archetype, and would be a fantastic addition.
Isn't that the same as they always were? They are the Sorcerer version of a Divine Caster, and more better suited to using the offensive divine spells.
Well, they used to be their own, separate class in 3rd Edition. So I was just clarifying for robertthebard that, if they're added, it will be as part of the Sorcerer class.
