it is true that when you learn the system well enough, the a.i. doesn't seem to be able to keep up, i am winning 6 and 7-0 during the last few games. I haven't upped the difficulty yet though, that's why i asked myself
I started the Champions Road mode and won the second match easily 8-0, without even trying at the end (I'm playing on regular three stars difficulty at the moment). And from the two online matches I've played I know that I'm not actually that good (by the way, the online play was totally smooth - no lag. It does take a while to find a match though...).
Maybe the mode just starts out easy, I've got no idea.
