AI in Might & Magic: Heroes VI

Another fact. I was playing with an allied AI of moderate aggressiveness, well, in terms of difficulty. It was the second or third week from the start of the game. I see a neutral Castle filled with elementals. The threat is deadly. So, I think, I'll gather troops, return in 3-4 weeks, and destroy it while the AI is busy with something else (and it was really acting strangely xD). But that wasn't the case! A couple of days later, my ally, with an army half the size of mine, calmly takes this Castle with monsters from its first four buildings, and, as I understand it, without a single casualty.
I almost dislocated my jaw from surprise :smile21:

To be honest, I haven't played scenarios because I'm playing through the campaigns. But judging by them, the AI is a complete loser because, playing on the highest difficulty (in campaigns), it is defeated easily. So, I don't believe those who say that it is difficult to play against it. Although, I can assume that it might be difficult to play alone against 7 AI opponents in an alliance.
