Steeliest of the dragons
Regarding priests only getting access to part of a domain, isn't that basically the same as splitting that domain up into its constituent parts as separate domains? I mean, if you have Nature (Animals), Nature (Plants), Nature (Plants, Weather), etc. isn't that the same as having Animal, Plant, and Weather domains?
Mechanically, yes, I suppose it is.
But for presentation and immediate flavor, I think having the overall category is much cleaner and easier to swallow (not to mention page count) than listing separately: Air, Animals, Battle, Chaos, Civilization: Urban, Civilization: Rural, Currency/Trade, Death, Despair, Destruction, Dream, Good, Earth, Evil, Fire, Healing, Knowledge, Law, Magic, Moon, Plants, Prophecy, Protection, Secrets, Shadows, Stars, Sun, Trickery, Undead, Water, Weather...etc. etc. etc...blek!
Not to mention the need to then come up with enough spells to fill all of them, individually. If you have 2 or 4 spells dealing with animals, 2-4 spells dealing with plants and 2 or 4 spells dealing with weather...you have nice 10-ish list of a domain can call "Nature" without the bloat/stretch to come up with spells just for Animal or Plant or Weather...and if, say, there is no 5th level spell for plants, that's fine cuz there's a couple for animals and weather. Then, if you don't want or have access to those, for 5th level spells, the cleric picks from some other sphere they have access to.
Make sense?
