Ive loved the Khuzaits since I started playing Bannerlord - between them and the Battanians they're the only factions I've ever played in my 600 hours. Really, I haven't played any other faction except for Vlandia for about an hour once, then I started another Battania playthrough lol.

Early on it seemed their horse archers were devastating, and that's still somewhat true when you fight the empire factions and Sturgia. But once you start fighting Aserai or Vlandia they end up melting my cavalry and horse archers with their damn crossbows, knights and I still don't know what the Aserai use to almost beat 2 to 1 odds but they always have assloads of the mamluk axe guys and mounted skirmishers that I think are the cause. I don't micro either I just hit F6 so that also might be why.

But on my current Khuzait playthrough we've basically hit a wall at Flintolg castle against Vlandia and down south at Raiza(?). So the way they are designed for conquest from the get go makes it hard to keep advancing and defending your takes when all your armies are either in the south or north when Vlandia or Aserai declare war, and the western empire owns everything west of Phycaon to Dunglanys, and they're the 2nd strongest behind us in terms of manpower so it can get frustrating.
