I've played 70+ matches now with the full release and no matter the team, this is the CPU's go-to attack, making up I'd say 90% of their truly threatening scoring opportunities. I do see different approaches in build up play, but once they're in the final third, it's pretty much all the same: ball to wing and low cross.
I've seen one long shot by the CPU - it was by Griezmann and I remember it because I was shocked - and only a handful of headers. Like someone else mentioned above, players like Hazard are nothing like the real thing - you rarely see skilled dribblers taking you on and rarely do they do much in the way of feints and skill moves.
But the defensive AI is just as bad. All this talk about the low cross and lack of variety in CPU attacking play ignores some major flaws in the defensive AI. It's interesting that you mention the better positioning because it seems like the positioning and tactical instructions are still overriding contextual decision making.
For example, here's a video where I'm dribbling down the wing and CPU midfielder begins to track me but then just stops, as if bound by his position:
Here's one that I can't explain. I have the ball on the wing and the CPU defenders aren't bothered to close me down:
Here's another one in which the defender just stops and allows my winger to dribble by:
And speaking of low crosses, one of the reasons the CPU scores so many is because of poor marking. Here's Van Dijk - one of the highest rated CBs in the game - make the baffling decision to stop and watch the cross go to the striker rather than react:
Also, I know that you said positioning is better in 19 but the backline defending is so concerned with dropping deep that not only do they make it easy to clear the ball to an open attacker, but the entire backline often won't bother to close down until you dribble to the box:
Don't get me wrong - I'm enjoying the game. There's so much it gets right. But I don't imagine this lasting long if the AI is not fixed because between the CPU attacking AI and the general defensive AI, this is some of the worst I can remember from PES. And these defensive problems I'm seeing, this is like FIFA 15 all over again.
