I played the game a lot when it came out of early access and didn't play it for about 4 months or maybe more. I don't remember this happening before but it seems like AI cav only attacks downwards, which means they just basically target my horse only. This is really annoying because you can't really defend against it and on realistic difficulty your horse goes down in 1 or 2 hits even with decent armor. Am I the only one that has noticed this behavior?
