I have altered the magic-user class a tiny bit for my Middle Earth campaign. Let's face it, we all know that wizards can swing swords, because Gandalf does it! So here is my write up for Holmes Magic-Users:
Magic-users — humans who elect to become magic-users cannot wear armor and may carry only a dagger or a staff for protection. They can, however, use all magical items, but not magical weapons (other than swords or daggers). They have the advantage (shared with Rangers and some elves) of being able to work magical spells. At the start, however, they can cast only one spell and must advance a level in experience before they can learn another. Thus the magic-user starts out as an extremely weak character, but if he survives and rises in experience, he becomes increasingly powerful. The types of spells and the way they are used are discussed in a later section. Magic-users, of course, may be good or evil, lawful or chaotic, and most of their spells remain the same.
As you can see, magic-users can now use daggers, staves, and (only) magic swords. They cannot wield normal swords or weapons, but they have an affinity with magical swords. Now, obviously due to poor attack tables, and no armor - most magic swords should be given to fighters first - but if more than a couple are found, feel free to let your wizard have one.
