The problem with world gen is that now it makes these massive holes underground that makes strip mining extremely annoying. You either make a bridge across 100+ blocks of dark cave, or round around said cave lighting it up and looking for ore. It’s just exhausting and you don’t even get coal while you do it.
It just makes the underground more tedious since you have to dig around anyways. If you could get around without having to dig and build constantly, and just play it kind of like a dungeon crawler, it might have opened an alternative way to find resources. but it’s just more walking around an unlit cave, half filled with water, fighting for uiur life to get what looks like diamond from a distqnce but turns out to be somtbing else once you get there. If there was another level below all the holes that was just blocks and ore, that might let both things exist at the same time.
