Agreed. For all the whining and complaining about the lack of ores when the change was first implemented, my miner hasn't been suffering from lack of any ores except a giant pile of iron to fill bods.
Then again, I work with both the prospector's tool and the gargoyle pickaxe. Even the lowliest iron site becomes a shadow spot when one doesn't fear the elementals.
Honestly, my smith/miner has had very little occasion to actually USE valorite. Oh, she has a heap of it in a chest, but since valorite bods are far, far rarer than the ore itself.. it just sits there. The reading glasses of the trades aren't all that exciting, and miners don't get an option for all the useful stuff the lumberjacks get from the museum.
Apparently the museum doesn't appreciate miners. Let that place burn down once, oh yeah. They'll be looking around for miners that can dig up granite, and I'll try not to be too smug when they do.
