My wishlist is an impossibility...
I would like to see gods that are more like the RealWorld counterparts -- messy, confused, overlapping, internally contradictory, etc.
Take Zeus by way of example. I'll leave alignment out of the picture (a massive headache), but simply take his portfolio.
He is a god of wind, storms, weather, lightning ... but if it is a storm at sea, this usually falls into Poseidon's hands ... but there are tales where he releases storms on ships. He is the king of the gods and thus the exemplar of how to rule ... yet he is constantly manipulated by his wife ... and his children ... and his multiple lovers ... and even some of the lesser gods. He is a randy little fellow, constantly looking for new lovers, constantly forgetting about the old ones, although willing to lend a hand to a child, especially a male child, later one. He is petty and vengeful, contravening his own laws at a whim, then suddenly feeling constrained by those very same laws.
There is a shrine to Zeus in Greece: Zeus, Who Drives Away Flies. Kinda hard to fit into a folio.
D&D gods are neat, organized, very slick, clean, shiny and modern. They fit modularly, neatly stacking with other gods. They cause no headaches. You hknow exactly what they should do, how they should act, that there parameters are.
D&D gods all have
borders. Real deities have
frontiers.
