I really tried to like the demo because I was really surprised how good the beta was online. However after a day playing my friends pointed out that dribbling is too easy even on superstar. So to test the theory I played as Barca on superstar and decided not to pass very much and try straight dribbling every time I got the ball. I won 5-2. Previously when playing the game the realistic way I was losing to the AI on superstar.
So then I thought ok, this was Barca and they have some amazing dribblers, although Umtiti is not usually in that category and he ran from his own half to score

Sadly it quickly became apparent that this was a thing and dribbling in this game is broken. Here you can see an example

The AI doesn't close you down or block your run, they don't even have the pace or strength to outmuscle you off the ball. It's utterly bizarre how they say this took 3 years to make and nobody in that time noticed that all you need to do to score is dribble straight at the goal.
For online this isn't an issue as human opponents wont take too kindly to the opposition just running at the goal and shooting. But for offline on superstar difficulty, if this isn't fixed it's a game breaking error.
I've been accused of not being a proper PES fan because I'm trying to highlight this error which is complete nonsense as I want to play this game and enjoy it and until this is fixed PES2018 isn't a game, it's a 3D render tool. If the only way to enjoy PES2018 offline is to pretend you are barca and do lots of nice passes then PES is dead.
