I gotta say, reading your replies about the Ai fixating on a set target and ignoring everything else does ALSO seem to be part of it. That said I think my own comment about an almost complete abscense of blocking still stands. I did a tourney today and noticed that my companions with high skill in 2 handed were reliably LOSING to people who had **** all in 2 handed skill
Im talking a 111 vs 27 (their current stats) differences. The 27 ones beat the higher one 3 times in this tourney alone

in 1 of the fights the 27 skill one was even wounded while the other wasent!
So clearly skill in the weapon group makes **** all difference. Neither party ever tried to block or feint either. Just randomly flail their weapons at their opponent. Wtf did they do? When the game came out combat AI was absolutely FINE! Challenging in some aspects even! And not this....mess!
