What you are talking about is making the player worse and not making the cpu better. This is a constant problem with EA sports games.All of that can easily be made to happen in the game with just a few slider tweaks. Even more so when one edits the db. FIFA 18 can be changed from arcadey to an exceptional football game, it just takes a bit of effort. The sliders alone can fix every one of those issues.
If you win 10-0 on legendary and are ping-ping passing with impunity, it's because you're using assisted controls. Play using manual controls. Lower CPU shot/pass/first touch error to 10 and raise User shot/pass/first touch error to 90. Raise CPU speed/accel sliders 10 points above yours. Etc. No more 10-zip games.
I rememeber rory mcilory golf on the ps4. The ai was hopeless. EA refused to make the game a challenge and the only way to make the batter was to make you the player worse. This is a negative,
I tired the game again last week and ea have added courses but done nothing to make the game ai harder.
There our thousands of people asking ea to make the game ai harder and they absolutely refused to even acknowledge them. Consequently the game flopped. But EA did not care as they maintained their power over their games. Thats what its really all about. Power and control. Ea are masters at that. Its not going to change.
