There is an option.
You have to display actual examples of martials at various levels and build the classes to that.
The core issue is the designers of D&D and most D&D clones have no desire to run nor look at the progression of martial classes past level 7 or so.
Just progress the barbarian from Angry Warrior Dude to the Hulk. If you get to level 20, and haven't created a Hulk... throw away the draft and start over.
That's been my suggestion before (using the Tiers of Play), and I would love a solution like that, but it steps on the toes of people who just want martials to swing a stick and bonk a goblin -> orc -> demon -> dragon -> lich.
I'd love to be proven wrong, but I think WOTC is so risk averse, you won't see it in this space.
