So I made Ceresa my vassal, and start looking at her traits.  She is a summoner and took Assassin as her class.  Kinda gimped herself.  She can get two Shadow Wargs.  Maybe Summoner should get bonus summons that work with each school of magic if AI can't plan ahead?

Also, the four AIs I conquered this game are still holding/buying extra wargs and extra venom sacs the AI should be cashing in for gildar.

They are also not prioritizing their weaponry properly, Kulan had the Hummingbird pike (ATT 18 + summon Air Elemental) and was using a Broadsword instead.

Ceresa was wearing a padded vest and not a spellcasting robe that gave same defense and additional bonuses. 

BTW, Thanks for fixing the Aegis Cloak (added +5 dodge)!  Love how you guys listen to us forum dwellers!
