Yes I think it's almost impossible to create a perfect AI that can satisfy everyone, which is one of the reasons why I strongly oppose co-op in RE 7.
I saw you in the comment section then I thought "quick I gotta post this on the forum before Airaku does" aranoid:.
by the way we got a horrible news, recently a stunt woman working on the final resident evil movie had a major accident and the doctors put her into coma. I hope she recovers and will be allright.

I really hope she recovers and is okay... she sounds really amazing and talent. I'm surprised I've never heard of her and she sounds pretty amazing. Even if I don't like the movies I got to respect her. Speaking of the movies and Capcom's reluctance to support them (Anderson actually went to Japan to get info on upcoming games to try and fit the games and films in better and they wouldn't tell him anything -_-) take a look at the White and Red queen in the originals. I never noticed it until a couple of weeks ago.
When you see it 0.0
As for the A.I.... I almost never had a problem with the A.I. in the games. They hold their own fine and actually fight enemies off. MUCH better than the majority of co-op games and/or games with other A.I. controlled allies xD
