Yep, many are.
I think the auto-learn concept is impossible to fix, simply because you'd have to *yze so many players, and no one has the time to do stuff like that.
However, the opponent team doesn't get to play manual either, so I suppose they thought putting auto would be more fair.
My only real suggestion is for you to learn how to beat the opponent the first time you fight them. You can tell which of your ninjas will launch first, and there are plenty of those information around the forum.
