Maybe a wizard is really booksmart (gets a positive modifier to rolls where arcane or non magical knowledge is required) but horrible at casting spells (gets a negative modifier to combat rolls). As for wands themselves, maybe their construction was done by someone other than a professional or by the character themself. Which would make them weaker.
