OK, so your talking about a completely different game. So why are you ranting here in a 5e forum? There are general forums for that. Have you tried Exalted? That sounds like it would be more your thing.
Alternately, if your stuck with 5e like many people are, simply add those to your game. There is already a model for it after all: 4e. 4e gave those type of abilities to martials and the concept would be pretty easy to implement in 5e. Like 4e, just re-fluff spells to be martial exploits. I have seen some 3PP products that did this for 5e already (convert 4e martial powers to 5e).
However, you could do those things in the theoretical game I have been talking about and for some reason you seem to want to trash the idea despite it aligning somewhat with your sensibilities.
It just comes down to balance issues, like this very thread. People see the disparity between martials and casters, because they aren't blind. There are two solutions. Try to nerf casters, which the system really isn't mean to do (there are issues inherent to the system that casters are apparently designed to solve- there's a sidebar in Xanathar's that discusses this point when it comes to resistance to non-magical b/p/s damage), or to do work on the back end to make sure your caster light/no caster party doesn't encounter these, or have other ways to deal with them.
Or to take the limiters off the martials and allow them to have "supernatural" abilities of their own. There is a bias on the part of the game designers- they look at a subclass and say "ok well, they are magic, so they can have any kind of cool ability", then look at another and say "oh this guy can't have magic. better give him...uh, I don't know, advantage on an ability check or something".
I understand the desire to have a narrative of the "ordinary man in an extraordinary situation" but even 4e ran into problems here.
Any power source other than Martial could, for example, get a power to teleport. And the Ranger actually got such a power because they had a slice of the Primal power source.
So there was this entire design space that the majority of the other classes could have, that was locked off from the Martial classes because "that's too magical". By contrast, there was
nothing unique to Martials that other power sources couldn't have.
You see this continue in 5e- Bards and even fugging
WIZARDS can get extra attack!
So for the health of the game, the narrative should change, because otherwise, in order to have the desired narrative, you have to spend a lot of time and energy undoing what the developers have done to the game.
