Giving all wizards everywhere expertise in Arcana as part of their default kit does two things. It cements the trope that all wizards everywhere are massive bookworms and lore nerds, and makes it impossible to make a scholarly wizard who is more focused on theory than his peers because you cannot have better than the universal expertise that all wizards now have.
