In H5, you simply watch how the AI conducts a battle. If you don't like it, you play yourself.
In the H6 beta, I was disappointed when I didn't see this. There was a function to calculate everything automatically, you could only calculate battles with neutrals automatically, or you could calculate nothing. But it was impossible to make a choice after each battle. What about the release?

Because the hero is a mage, and without using magic, almost every battle threatens losses.
