If spellcasters were balanced compared to martial classes before they start casting spells, what happens to the balance when they start actually casting spells? You'd have to basically have no spell recovery at all to get close to balanced.My personal belief it is the spell casting system in general, and the interaction with resting. Spellcasters need to be balanced to be able to effectively contribute even w/o spells, like martial classes are balanced to function w/o magic items.
Come to think of it, most casters are already balanced against a lot of martial classes even without spells. The worst of them have access to ability checks and skill proficiencies, and player creativity and role-playing. That is already as good as the Fighter for example.
