Witches have an odd progression for Cure spells. It doesn’t follow the Cleric Cure spells progression, skipping 3rd level than continuing on. The Druid also has the same odd progression for Cure spells. Is this an error? Should the Witch and the Druid be using the same Cure spell progression as the Cleric? Another Witch spell question. Shield is not on the Witch’s spell list. Is this an error? Only having mage armor means Witches have a low AC, especially at higher levels.
I don't think this is an error, witches have more in common with druids thematically than with clerics. Witches have a less diverse spell list than wizards, sprinkled with some druidic magic, but less utility and versatility. You could still get shield of faith instead of shield with the proper patron.
