Heroes 6 - Discussion

Can you explain it in simpler terms?

The hero loses all movement points, and the mine doesn't generate income for 7 days. However, it remains under its owner's control. There's also a clever system for capturing mines now, which is similar to Disciples: to claim a mine, you need to have a town nearby or build a special fort. Heroes no longer capture mines directly. So, it's quite useful. As for the Crisis, I don't know, sorry.
