I know that fighters aren't wizards, and I see how they have been structured to play differently than wizards: with different strengths, weaknesses, and abilities to let them fill a different niche in the game. How is any of this a problem? There are several threads in play now about "fixing" this "problem" and I don't see it. What exactly are we trying to fix?
But there's no way I would post this question in any of those threads, though. No sir. I've already seen what happens when people ask such questions in there.
And as a corollary-
Zeno: I want a good fighter!
Achilles: But there is a good fighter. I like the D&D fighter.
Zeno: No, I want an awesome, super-cool, superhero fighter. Like anime.
Achilles: Okay. What do you mean by that?
Zeno: I want a fighter that isn't constrained by regular fighter stuff. I want a fighter with a blade that booms, and that can jump like a spell, and can do all the cool stuff that spellcasters do, but is also a fighter!
Achilles: Have you tried an Eldritch Knight? Magic Initiate? Multiclassing with a dip? You can just add a few spells, like, oh, booming blade. Or jump. And then you have your fighter and all your cool effects, just like a spellcaster! You can totally have your anime cake, and eat it too!
Zeno: NO! I want a fighter, not a spellcaster. I don't want to ... CAST SPELLS.
Achilles:
