This is literally the only thing keeping me from playing Zelda. It's not just that the weapons break so easily, the interface for switching weapons is tedious and immersion breaking. I understand why folks beeline for the master sword to avoid the trauma and time wasting of weapon management. They literally could have left that part out of the game, or double/tripled durability and it would have made for a much cleaner feel.
Meh I've been playing botw since launch. I learned to used the slate powers a lot and just stock up on weapons. Even on Master mode where mobs have a lot more hp I haven't had many issues. I found it annoying at first but by doing lots of shrines you get plenty of weapons.
