Quite the opposite the AI has gotten weakerI like the new combat A.I and find it more challenging compared to pervious updates of combat A.I. I play on Bannerlord settings and in pervious beta's found combat way to easy, to the point of being boring, After the update when i first tried it and the guy blocked me i was shocked and thought at last there not stupid. Yes they now block a lot more which is realistic. What's unrealistic is not blocking attacks. The pervious A.I cavalry was useless vs foot troops and just rode around them, but not now they kill them but this could still be improved. Thing is if it too hard for you lower your Combat A.I settings. But people want a bit of a challenge can play on Bannerlord setting, that's why there's difficulty settings.
For example, Cavalry stopped hitting infantry at all. You think the AI is better because it's a little better at blocking , but the AI is still very easy to beat on max difficulty.
