Take scrolls out of this game and there will be nothing left as it has literially no loot diversity or crafting, its like taking DOS1 removing all the features and putting in a slightly above average story while dumbing down the combat.
Pretty sure OP is not suggesting the removal of scrolls, but a re-balance.
In my opinion scrolls should only feature wizard spells (because that's how wizards learn their spells after all), and not divine spells, which come from the practice of religion. Not sure about the DnD rules about that, but thematically that would make sense to me. Also scrolls should be more rare, to make them more valuable.
