It isn't "laughable" when those other casters have other features, such as wildshape, channel divinity, metamagic, invocations, and inspiration--none of which a wizard has.
Yep, I agree. Part of the issue (primarily with wizards) is the incredible amount of versatility in their spell list. Many spells which make the other pillars non-issue could be class features for non-casters, including a spider climb ability for rogues, which I always thought was appropriate.
A different role in the game? If you wan to be more of a support PC, you have more feats than other classes. Take the leadership feat and give everyone temp HP. Maybe take the protection fighting style so you can protect allies. Fighters aren't bards, but neither is any class that isn't a bard.
If you want to open locks, take a background that gives you lock picking. Or just bash the door down, it can't be any noisier than knock which is audible up to 300 feet away.
Or that the caster can cast on the fighter if the situation calls for it. I mean you could give the fighter the ability to fly if you want, doesn't mean it would fit the theme of a mundane fighter that's just really good at fighting. In the other thread people are saying that an MCU character that matches would likely be Captain America from the MCU movies. Can Cap jump 60 feet with a running start? No.
Huh? It's called plate mail. Take the defensive fighting style and a shield to get AC 23 before magic. If you're dex based consider defensive fighting style and two weapon along with defensive duelist. In either case your AC will better than the wizard. Then again your fighter can have double the HP of that wizard, even if they do get hit more it's not a big deal. I don't see why it's a big deal.
The key words there being "part of", where they - annoyingly - leave undefined how much of your turn that part represents.
"Seek out" does not equate to "find".
Dirt-simple answer: relax the attunement-slot limit for Fighters - instead of a flat 3 make it 1 (or 2?) at 1st level plus 1 more at each of 4th, 7th, 10th, 13th, etc.
If one takes care to select their spells, they will have a highly optimal spell for 99% of situations (and that's with never preparing an alternate spell list) - perhaps not the most optimal spell for a situation, but even a highly optimal one is stronger than the fighter in most situations.
Maybe because you're the party pack mule i.e. the one who's strong enough to carry them?
No, but he could and did plan for cheaters; which is what you'd be doing here.
I'd specifically try to do the opposite: make one useful in one way and the other useful in another. Between them they still wouldn't cover all the bases, and nor should they; ideally you'd need at least three more characters to even try to cover them all and even then there'd be holes.
