I have yet to try the new patch, as I have turned on my gaming PC for a week now. Work seems to be getting in the way.
But as of the last patch I thought the AI fairly good, a few exploits that people have found, but no show stoppers. We have to remember this one is not a Matrix Games War in the Pacific
Remember a lot of beginners play this one as well, and I am sure the game will get better as more patches get released.
