I do agree with more dialogue options, even if they end up like say the mass effect/dragon age dialogue where functionally not much changes.
On buffing and stuff like that, technically religious classes already get those through channel divinity. They are not permanent buffs but they are a channeling of their faith. Additionally all their spells are faith based. HOWEVER, I wouldn't mind camp activities happening even if they don't give anything mechanically. Religious characters praying, a Ranger skinning a boar, a wizard studying in the corner with books, I feel like just showing them do this stuff would do a lot for making the camp feel more alive.
