So recently in my game I braved making the unstable ingots to make a deep dark portal (And died twice in the process), and frankly I'm unimpressed. From most of what I've seen, once people have the portal, they quarry in the Deep Dark, and I can't figure out why. From how many people do it, I expected so many ores I couldn't even understand it, but frankly, it's less than the overworld, with how abruptly it cuts off, so I'm curious if it's just a reason I'm missing (I haven't done a whole ton of exploring), or if the only reason people quarry in the deep dark is because they don't feel like messing up the overworld?
