I've always found it ridiculous that the excuse of "It's magic" lets the Wizard do any crazy physics breaking thing he wants, but the Monk who literally trained so hard
I agree. This is one reason why I prefer low-magic games or even games where wizardry is largely the domain of NPCs. In PF1, we used house rules to limit Wizards. Its much easier to keep them from casting.
You, for instance cite Beowulf and might point to the 2007 movie as an example. I too would cite Beowulf, but I would point to Eaters of the Dead, aka the 13th Warrior.
Alas, the DM of PF2 game I'm in generally likes the ultra-fantastic. He's a good friend. I just have to live with it. My other regular game stayed with PF1 and has all the house rules. At least half the time I get a game I can usually remain immersed.
