The mod makes it appear that the computer is using sacreds better. From what I've seen that is not quite true.
It still uses apparently random, quixotic blesses, based on whatever logic it uses to make pretenders. But because of the limitations on available recruits and the removal of the capital restrictions on sacreds, there are a lot more of them.
But that alone is better. More sacreds with any bless is better than a larger quantity of mediocre 10 HP/8 mor spearmen.
(The above is just an attempt to see more of the cool icons.)
