Legend
But if the genre is mythic... Jamie Lannister isn't representative of a low level mythic fighter since he's not a mythic character at all...
I don't understand what is happening here. How are we not connecting.
In your 5e Mythic Campaign, pick a 4th level genre archetype for your Fighter. Now pick a relevant noncombat obstacle for them.
Now do the same for your 20th level Mythic Campaign Fighter.
What does this look like. Does the system architecture support this fictional framing and disparity?
