@Arperum Caves do give you more ores, but in average, per hour, you will get like half the diamonds and emeralds. Which is the only thing you're mining for if you have 43 stacks of iron :)
@RudolfL.Jelínek They are playing modded, so you need a ton of resources, not to mention that some stuff that rather useless on vanilla, like gold, are used a lot in modded
@DH. gold, by my statistics, is about the same frequent when cave-mining and branch-mining - cave: 307 gold in 15 hours, branchmine: 298 gold in 15 hours.
There are two active roomowners who would slap you silly if someone went mad. (Making them play with me and follow in my insane plans counts as slapping silly, so does out automating @KevinvanderVelden)
