eb generals

how do their stats work?

I get command and loyalty, but what about influence, authority and confidence? and what replaced the acumen ability that made for a good administrator? i kinda don't understand what i should be looking for now.

Influence increases public order. The higher his influence is the happier the people he governs are.

Confidence increases morale in the battlefield. More confidence means soldiers break and run less easily.

Authority... I am not sure, but I believe it influences the chance of other generals rebelling. More authority means less rebels.

I don't know for sure what replaced acumen. It could be command or it could be traits.

thanks.

another question, what happens when i enslave settlements or armies? i don't see any noticeable increase in population or income due to trading.
