I disagree on the cleric. Clerics were usually one who travelled to spread the word of their lord/deity. But suppose you could look at it in the terms you put, but I wouldnt do that in my game.
Sure, but not all clerics need a religion that involves deities as such—philosophies, ancestral worship, animism, and more all exist in the real world, so there's no need to put a one-size-fits-all on the cleric. Heck, then there's polytheism and monotheism as opposed to D&D's default of henotheism. Even in 2e, The Complete Cleric's Handbook went into clerics of philosophies and such. I think having different cultures in a setting approach religion in different ways give variety and is more interesting than one where there is no variety.
