Learn something new everyday. Although I suppose it can still work since I am sick of Boss I-NO, still not correct though.
So now, instead of qualm, I mean *problem.
And I agree training mode is great, you can put in an hour and have it feel like nothing. The computer is quite crazy if you put them on the max level, they RC and FRC like crazy and can do super air juggles as well. As qwerty and tolore have both said, playing other people of course gives you a better experiance in terms of challenges and the computer can do things that normal players can't even dream of.
