I was in the beta and I do not think the team styles were in the beta. At least I hope they were not because the AI did some weird stuff.
Very fond of getting the ball quick to a midfielder and then he looks forward to the lone ST and plays the pass to him? Huh? He is bracketed by both cb's and my rb and lb are just staying in formation because there is no other AI player within 20m
So I just tracked back and constricted the ST with my MF's and got an easy turnover over and over.
The AI was obsessed with pushing the ball forward without numbers.
The main AI method of scoring in the beta was to plant someone around the 6m box, then ping pong passes around the box abusing the delayed and incorrect player select system the user has, until they could serve a quick pass into that ST who would then shoot not facing the goal into either corner.
I tried offside trap, I tried pushing my line height up, nothing would keep my back line from staying below the dude planted at the 6 box.
It was a beta, not sure of the build date. I would be shocked if this AI was in the upcoming demo or full release.
I was also in the beta and I agree with you. I did not notice team styles at all.
