It seems like I never see anyone wanting to narrow the martial/caster gap in the name realism, associated mechanics, simulation, verisimilitude, immersion, or whatever...
but the thread is
[+] Ways to fix the caster / non-caster gap
what's a verisimilitudinous immersive realistic way of doing that?
Well, piling on restrictions & limitations on casting and magic like in the olden days... maybe adding dangers and consequences to it's use and abuse?
...maybe ... while ideas like those do reduce the overall utility of magic, in theory, they also make it more and more central to the play of the game...
