It occurs to me that wizards scribing any spell only feels like an issue for clerics, though druids are in the same boat. It could be because cleric spells (like Bless) feel more intimately tied to their class than druid spells (like Flaming Sphere). Or it could be because shapeshifting gives the druid class a strong identity, while clerics' ability to channel divinity doesn't feel all that special.
Though removing wizards' omni-scribing ability would help make clerics feel unique, I do wish their distinctions extended beyond just their spell list.
