If you had a prepared caster from a full spell list (cleric, druid, etc.) with an alternate class feature that said, roughly "Instead of preparing from your normal class list, you can prepare spells from any class list, but only spells that belong to X school", how big of a power downgrade is that? I'm thinking it depends on the school, right? Evocation and Conjuration would be a minor nerf, but Divination or Abjuration would be a pretty big downgrade.
