A question about AI generals

[Aper]

So this means the stars are less important than the morale boosting traits and even harder to get.
Then what are the stars for?
Sorry if these questions seem stupid but I'm not an native speaker of the english tongue and thats why I probably miss sometimes the point.

Stars give a bonus in defense and morale only to soldiers near to the general AFAIK but are hugely overpowered in autocalculated battles, so you are often forced to fight on the battlefield if you don't want your Thorakitai Agemata Basilikou to be slaughtered by a bunch of peasants led by a 10 star AI general.
EB team gave AI generals lots of stars to grant them superiority against the player at least in auto-resolved fights.
