No matter where you go to do missions, they're still nerfed and it's hard to even get just one.

This is my opinion, but I believe the mining system is fine the way it is. The machine will give random minerals yes, but I prefer it than actually going to different machines for certain minerals. Because I'm sure that machines used mainly to get minerals for repairs will be crowded.

Edit: do you think they will really put in seperate mineral machines? Especially like the more expensive minerals like diamonds? I doubt it.
