I'm having a problem with some of this ... especially the part about the tomes etc.
Look at for example the tome series Samurai. Badass Melee fighter who actually has the commune with the ascestors power. You can actually push that to higher level shit if you really needed to.
The Tome fighter seems to be able to play at all levels, is that not true?
It seems to me that the op's problem with people who hate that the fighter become weeabo fightin man.
Well I'm kinda like ... wtf. You just can't appeal to everyone. Thats the problem you cannot appeal to everyone. period. It stupid to try. If someone says its okay for your mage to go from harry potter to Doc Strange but it violates thier WSoD then there's certainly a level of "Kiss my ass" that should come with your next response.
Oh and by the way a quick 3 badass normals off the top of my head would be. taskmaster, bullseye, and desthstroke the terminator.
I also note that most of the things that people talk about is
1. Travel
2. Various combat tricks.
1. On travel.
Whatever the fighter has to do to get the plane of shadow. Everyone else needs to have to do aslo. I really feel like to get the game that people expect on some level. You totaly HAVE to travel to one of the "Gates to the Outland" to get there.
Or it has to be a ritual that any 4 fucking people can do if they have the sacred scroll of cytorack and can read the old tongue. Its pretty much a no brainer.
Also if you're going to have the pally summon a gold dragon to ride on then we need to go back to the old rules of domestication.. 2nded I think. In which the fighter can force servitude out of said dragon after he kicks the shit out of it and spares its life. (of course it should prolly get a save for this) or whatever.
2. On combat and related things:
Lets say I sit down and I want my combat gimmick is "I blade all kinds of shit... to death". I should totally be able to do that. Not only should I be able to do that but I should do that well enough that it fucking matters. Frankly cause people are going to play the guy who swords shit down. No matter what.
I don't know if the phallic imagery makes em feel manly or whatever they're gonna do that, and it doesn't matter to some if its a feral death blow or a 10 full attack spread or, foil, foil, foil, epic attack. People want that to be there.
So the people who don't want fighters to have nice things are the ones that are wrong.
In the Zombilypse scenario. Where you want a fighter to stop the town from being zombied. ... people need to fucking read the zombie survival guide, and read world war z for these types of arguments really. Frankly cause before the zombie shit gets world wide there are really plenty of chances to stop it. People just totally fuck it up cause "the don't believe in zombies" in D&D everyone KNOWS there are fuckin zombies so the million man zombie army actually can be stamped out in its infancy.
IF NOT then the figther has to have to town construct a wall around itself, and tell them to close the gates and then he plays dynasty warriors for a thousand zombies or so, cleans himself up and give the town instructions on how to deal with zombie attacks ... in thier infancy.
If the fighter is faced with a gish making a magnitude 10 earthquake then he seriously has to have the option to kill that gish with extreme stabintaion in the combat minigame.
Alternatively, he has to be able to wreak the same amount of damage himself. In fact thats preferable. He's got to be allowed to kill a village or 2 in a few mins. .
Which I actually did come to think of with using this.
At 7th level, the critical threat range of any charge attack he makes, or any attack he makes against a flat-footed foe, increases by 1. (Thus, a greataxe would threaten a critical hit on a roll of 19 or 20.) This ability stacks with the Improved Critical feat or the keen weapon enhancement.
At 10th level, the barbarian can make a single turn, up to 90 degrees, during a charge.
At 13th level, the barbarian can charge through squares occupied by his allies or by noncombatants.
At 16th level, the barbarian can move up to four times his speed when making a charge attack, rather than double.
At 19th level, the barbarian acquires a "cleaving charge." If he drops an opponent on a charge attack, and he has at least 10 feet of movement remaining, he can immediately make a new charge attack against a second foe. If he drops that foe and still has movement remaining, he can charge a third, and so on until he either fails to drop a foe, or runs out of movement. All the other standard rules for a charge attack still apply, including the fact that he must have at least 10 feet of distance to make the charge.
Some acf for barbarians from city scape but remember doing that and having so much fucking movement that I thought... ubercharging like this I could kill a whole village in a round. Which is no fucking different ultimately from the gish sticking his sword in the ground. . .
There used to be soooo much talk about balance, then 4th came out and it was balanced in to banality. Not enough people ever talked about what no one not npcs, not pcs. No one should be able to do. Scry and die. Hell scry and teleport for that matter. Gate. There indeed needs to be some of that stuff that everyone HAS to go through. Yes you have to throw the ring into the volcano, sure you can teleport there; teleport clearly reads you can teleport anywhere you've ever been. ... wait what? That way the story can proceed at least.
TL;DR
What is the real complaint here? I actually thought it was obvious to everyone that the "Fighter" goes from Punisher~Taskmaster~Wolverine~Hulk or doomsday or whatever @ level 20. If you're confronted with people who are logic impervious about such things, they're going to be that way about other things. Likely not who you should play with. Those people really DON'T want the fighter to contribute. Nothing you can do about that.
