Hero
I think that there are probably two positions* when it comes to martial class capabilities:
The Heroic Martial position wants high-level martial characters to be capable of legendary feats, far beyond what would be regarded as realistic for a real-life human.
Cleaving anvils in two, swimming up a waterfall, grappling a giant, cowing an entire army with a demonstration of their power (or even without), climbing along the ceiling, lifting a mammoth, sprinting across water etc.
This is generally the position of people who want to be able to shape the in-game narrative as much as the casters can by, if not matching their capabilities, at least approaching them.
The Credible Hero position wants high-level martial characters to be very good at what they do, but not beyond the bounds of what a normal (but gifted) person could achieve. (Or maybe just a bit better.)
Cutting down a large tree in less than a minute, swimming, running and sprinting as fast as a professional athlete, even in full armour, grappling a small bear, convincing a powerful opponent to back down with a hard stare etc.
This is generally the position of people who like the thought that in a world where casters are teleporting, flying, creating illusory dragons and devastating entire armies, a simple length of steel with some guts at both ends can still be relevant in at least some of the fights.
*Naturally since these are viewpoints described on the internet, the actual position a person likes will fall somewhere in between the two, according to their opinions.
