Me and him played tons of practice games in which I get demolished in. But whenever I held off a push, scouted very well, defended off friggin 3 - 5 prong attacks from the blazing Terran 400 APM-age, I felt so happy. It's well worth it if you enjoy challenges.
I swear it is so easy to pick out who played BW competitively and who didn't just by watching how well they controlled their units. The "small" fundamentals that the B- players have, have a HUGE impact on the noobs in SC2.
