Certainly CPU COM AI have many flaw's! It's not perfect but stands better than pes2018! It's not so frustrating and disqusting like previous year. You will not see so many pinpoint passes from lower teams against yours. But I recommend to always lower the difficulty when you are playing with lower teams, increased it with more porewfull teams and when your team spirit goes well and you learn your team players, changed it permanently to your preferred challenging difficulty!
