If y'all think it's bad in ACNH then you must really suffer if you play BotW for when your sword or shield breaks during a fight. I agree a warning that it is damaged might be nice but it costs one customization kit to reset the durability back to 0. Rule of thumb is if you're going to be digging a lot then customize it every inventory or so. I do trees with my ax in batches of 5 to keep track since I'm shaking them with my net out anyway to catch any wasps. It's annoying, yes, but there are easy ways to work around it.
