Basically Khuzaits barely have any foot soldiers. Most of them are cav or cav archers się they are fast as **** and they always choose their battles. Autocalc is also in favour for them cause cav units get buff in autocalc and there is no counter for that. So an army of Khuzaits cav has advantage also in even numbered battles.
The AI cheat to upgrade cav without the need of horses in inventory is another thing that gives them advantage.
This simplified Auto-calc that just give khuzaits a battle bonus apparently even in sieges etc is to me a major, major flaw of this game. Ive been screaming about how an oversimplified auto calc system is a game killer -forever now- but it didnt have to be this way.
Lets look at history again since this is based off semi-quasi historical fiction - apparently the Huns (whom the Khuzait seemed based off of) had terrible footwear that were basically useless for anything besides riding horses. Is that in anyway used in auto calc to help temper their horse advantage? When is terrain and weather etc gonna start being factored in?
A game like this simply needs a more advanced auto-calc system to give us more interesting results in AI vs AI battles
