But let's think about the name-level wizard in AD&D, shall we?
First, they have no combat cantrips. None. Instead, at 11th level, they have proficiency in two weapons. That's okay, because you can only ever get three. Staff, dagger, dart. Pick two. That's your go-to. Not a scaling damage cantrip. But you don't want to be in combat, because you have approximately 23 hit points. Okay, let's assume you got max hit points at first level. You have 27 hit points. And a bad AC, because you can't wear armor. Which means that you can probably get taken out before getting a spell off. But even if you aren't, if you're hit, you still don't get the spell of. And unless you're casting one of a very limited number of spells (Magic Missile, Power Word), you're going to go last in a round.
