Lightning rods should oxidize

I know, I know, the argument "because it makes sense!" isn't really valid to most people anymore, but this is also more about continuity.

There has been weird features in the past like creepers dropping music discs, and they've strayed away from that with Pigstep for example.

This would purely be cosmetic. Weathered lightning rods functions the same as normal lightning rods, and you can wax them if you like the color orange over teal. Small continuity details such as this is what makes games shine!
