>>43306642The issue is that your "ideas" are not brief, but misleading.
You still are confusing what defines magic. Dodging a dragon's claw? Pretty impressive, and beyond the ability of most people, but that's not magical. Cutting a mountain in half? Carrying the sky on your shoulders? That's magical.
Balancing magic and mundane does not mean turning mundane into magic. That's just saying "Balancing the two is too hard, so I stopped even bothering with mundane characters."
Also, you really don't understand the appeal of mundane characters. You understand the appeal of physical characters or characters who have magical strength to a certain extent, but the character that who does not need magic is alien to you.
In literature, you can find plenty of examples of characters who defeat magical forces relying on nothing but cunning, craftiness, strong wills, and the limitations of their bodies. Them being the underdog is part of their appeal, but the fact that they are constrained and forced to work within practical limitations even when dealing with magical forces is what makes those heroes so attractive.
If your game doesn't have those kind of characters, that's fine, but to say a magical swordsman is actually a mundane swordsman is quite an unfunny joke.
Is it possible to balance mundane characters and magical characters? Yes, but your "solutions" are pretty short-sighted and impractical.
If anything, the best solution is to not discount the intelligence/cunning of the mundane, and to just make sure that mundane characters are given the appropriate mechanical bonuses and abilities they need to be good and diverse in combat. And, that's not really addressed with any of your solutions.
Mundane characters don't need to do crazy and nonsensical things, nor do you need to excessively penalize spellcasters by making their magic always a second-choice option.
