I like mining in the prison. There must be someway, though, to help out noobs that get stuck on the wrong side of the law. Let's say a noob kills his friend, another noob, and gets captured. He is sentenced to mine 20 stones. But he has no mining skills, and no way to train them! I support the forced mining, but there must be something for people with no mining skill, and no pp or trias to train it...
Also this stone must be slow to mine, even for people with maxed out mining. Otherwise, some might be out in seconds, while low leveled miners might be stuck for hours for the same crime.
But i do like the prison map.
