The issue with Diana's vulnerability really boils down to one thing, and it has little to do with her bracelets.
Compare Wolverine, riddled with several bullets...
...with Wonder Woman, nicked by the ricochet of a single bullet...
Diana being vulnerable to edged weapons isn't the problem. It's that she's depicted with no stamina against it whatsoever. Wolverine gets shot or stabbed, and it hurts him...but he's able to keep fighting. Diana? She drops like a stone. Theoretically, a two-bit mugger with a pocket knife poses as much threat to her as Doomsday.
I always say Diana being resistant to gunfire does not equal she's invulnerable or invincible or that she can never get hurt or wounded. She should relay on the bracelets to defend herself from harm. But I do think mere bullets and arrows and knives should stop being treated as legitimate threats to her.
