it could lead to really cool story/character stuff though like jjk: people born with broken bodies but incredible magical powers

Never miss an opportunity for unique challenges/stories.

It could be a hook like fullmetal alchemist or a realization for characters later: they are fine the way they are they don’t need to be fixed kind of stuff. simply discounting disabilities takes so much potential out of worlds/stories.

I mean that really depends on the world you are set in: if magic is everywhere/can heal anything someone who is blind could break immersion IF there is no good reason (he doesn’t want to see for personal reasons, it’s a curse and can’t be removed etc.)

However if magic treatment is rare/expensive of course there would be lots of disabled people (monster attacks, accidents, diseases, etc.)

Obviously thats not the problem here(the guys just a dick) but it’s something i run into a lot when designing worlds/characters: a lot of our real world problems fall apart if introduced into a magical setting.
