Metal does rust in water. Metal does not instantly lose half it's durability in water during a rainstorm. Unless you're from someplace where you've seen a brand new car reduced to a rusty pile after it gets rained on once?

Maybe they should cut that decay in half. It's that... Metal takes a loooong time to decay in real life, so for gameplay purposes it makes more sense for it to decay faster. Still, you should try keeping your iron and wood structures sheltered.
