What annoys me is that silver is actually a rare tin spawn, making it especially hard to find in the 2nd tier areas where copper is still much more common than tin. Also, the whole tin being useless without an equal amount of copper thing is total BS.
You can't really use Tin by itself, it's mainly used in alloys anyway. It's a soft metal, isn't it? I don't know as much as I would like about Metallurgy. Maybe I'll pick up a book at the library.
