This ultimately is the biggest difference this year imo. By changing pass speed, sprinting, and the defensive AI, the end-to-end sprint-fest and goal-fest that was last year just doesn't work anymore. None of the exploits I used last year have given me any success in this demo.
For example, my favorite team is Dortmund. Last year I was guaranteed at least 2-3 easy chances by spamming long diagonals to Reus. This year I haven't had a single such chance. And when I have found myself in space, the CPU defense is very good at recovering.
I'm finding World Class to be a nice challenge at the moment and it's been a struggle for me to create chances. Love how much more difficult passing is.
For me the biggest difference between this demo and PES is that with FIFA it's much more emotional. When I score, I'm fist pumping. There's a lot more "wow" moments. I am not getting that feeling with the PES demo.
