Look Batman works best as a street-level vigilante/ detective, fighting the mob, fighting dudes in weird costumes. when you mix him up with the superhero world at Large, he should be completely out of his depth I mean Justice League the Animated Series got this.

Batman: *seeing new genesis in the sky* I'm gonna need a longer grapple.

he should be using stealth and gadgets and theatrics by design, because fist fighting guys with guns when you're a normal person gets you dead quick.

Back in the day, Batman comics were more fun because

Him winning wasn't a foregone conclusion. He wasn't ten steps ahead of the villains. He wasn't immune to all their powers. He failed. He got hurt. He overcame his obstacles. That's good writing

making him into an invincible audience insert character has done him a disservice
