yes I felt the change too.I feel that moral has a more important role right now, usually my men fought until the last man but now if I have lost around 2/3 of men they start running. The same thing happens with the enemies, when facing small group of bandits I have to hold the fire of my archers otherwise they start running far before reaching my line.
And also, AI combat improvements or is it just me? (not just cavalry, and I mean blocking and stuff)
