Just my opinion, but having the Hero items be unbreakable allows for so much more experimentation and fun in TotK.
It’s the only mod I’ve got installed, and now instead of “Oh a unique trident that I can never use… wow…” I can play around with fuses and different fighting techniques without worry.
This mod also applies to the Master Shield and Master Sword, so I can surf around at my hearts content and swing away without having to purposefully break my sword after every fight so it’ll recharge.
I think TotK vastly improved the gameplay experience over BotW by making fuses increase durability. But the Hero items should have been made unbreakable.
