That is the issue, IMO, is there is no reason why you can't have these things, but for myself I would not have any interest in them. So, I am not going to take the time to develop them (unless I got paid LOL!).I don't know why mythic fighters can't replace some ability checks or saving throws with attack rolls or AC.
I don't know why you can say "My fighter is a demigod or god's chosen" so he gets an epic boon (from a list) at level 7 and 15.
I don't know why anime fighters can't get flash steps and air slashes.
But IME such issues are polar. A lot of people want mystic or magical fighters, others want only mundane but heroic ones. Two camps who could work together to help develop what the others want, and help ensure both results are balanced against each other, but most of us have too much going on to do that (at least right now).
