Partly true and also quite the opposite! Let me explain.
If I try to play the game like football, chances are the Legendary AI will walk all over me (not always). That is if I keep the ball more, make sure I face the proper direction before passing, taking time to control the ball, not spamming what is op, etc. Open space may disappear quicker for me, a high pressing AI may be more likely to catch me off guard and proceed to clinically finish with their fast passing and super accurate volleys. Was it my mistake? Sure. It's harder but not very enjoyable for me. Maybe it's overall a bit better than me playing like an idiot which is why I think you're partly right.
If I give up trying to play like that, and pass the ball just as fast I will escape a pressing game much easier, find plenty of space to counter attack and at the absence of space, launch an OP cross. Now it's actually easy to walk all over the legendary AI but still not very enjoyable.
Many people complained that the game is easy, but I think EAs choice is really between a game that plays like football and is easy for some people and a game that plays like crap (fut) and is still easy for some people. I think this will be hotly contested this year if the final game is anything like the demo. (The main problem here is that passing is ridiculously assisted and too accurate again this year, despite promising otherwise, let's admit that they have NOT delivered "slow, thoughtful passing", AT ALL).
I think they should tweak things slightly or keep all the AI bs separate in the new ultimate difficulty, but not sure how easy it is to do.
Also, this is overall a much much better game than fifa18, probably the best on frostbite so far, it's tons of fun (just not against PSG or City on legendary), and I will most likely buy it and find a combination of settings to enjoy it!
