Two wins seem like too little. I remember my first game on TC-3 in the autumn cup, playing with Wic, back then it was best of four, and we only played for the win. The tension was high, and we even argued in the deciding match.
But here, if you lose the first match due to a single mistake, you can only hope for a draw... I didn't really feel the excitement after the first match, to be honest.
I understand that maybe there isn't much time to play, although I would play, but less isn't better either.
