It costs an entire bar for a support that gives you the same radius as the old game's 2 nugget supports. With how much more difficult it is to get bars of metal (assuming iron ochre for iron ore, not bloodstone, bloodstone op) these supports really shouldn't be this worthless. At least they look good... right...?
Speaking of the rarity of metal, I am averaging less than a bar per FIFTY FIVE MINUTE smelt time. We're talking probably .8 or .9 of a bar per load, every 55 minutes. If the yields were increased and the time remained the same, I'd be okay. Or, on the other hand, if the yields were the same but the time was reduced to 15 or 20 minutes... That'd be alright, too. Additionally, I'm pulling 2-3 ore out of most of these walls. Some of them give me 8 or 9, but the majority still give me diddly. thx based rng.
My town started with 14 cast iron today. Five of it went in to a finery forge. I was very excited to hammer out some wrought. I poured in 9 bars, lit it for the short while it took to make the iron in to bloom, and went to check. I had a delightful 6 slag waiting for me, and 3 bloom. So, I move the anvil down in to the cave by the smelters and the forge, because it was in the claim aboveground for some reason. I hammer out the wrought... Cast iron. Okay, next one... Cast iron, and then I notice one of the other blooms turned to slag because I just wasn't fast enough to hammer it out.
Why the hell should I even keep mining?
(Don't even think about how the bats weigh in on all this. It's terrible. I have also done my best to provide information here as accurately as possible, with no exaggeration. I really wish it was exaggeration.)
