Opinion on reducing air exposure

 I understand that the goal is to make specific ores more difficult to obtain, but I'm not exactly sure how to feel about reducing or completely removing air exposure. Having specific ores unobtainable through caves just makes it almost pointless to explore caves and discover the new biomes. It instead encourages players to go through the long and boring process of strip mining.

 In my opinion, ores should be more common in caves than in strip mines. It makes it more of a challenge to obtain the materials and items you need in order to progress. I like the idea of having to search for what you need whilst fighting mobs, traversing lava pools, and seeing the new types of caves.

I hope my feedback is noticed. I will keep in mind that this is still an experimental snapshot.
