Needless extra effort
Why should someone be disqualified just because they forget to save the replay?
Also, watching up to 6 players replays? That will take forever
a) It takes approximately 10 seconds to save a replay. Add another 1 to 2 minutes to pack it up for upload. While uploading, jerk off, rebuild your company, or look for another game.
So you wasted 90 to 130 seconds of your life getting a replay to the guys running the tournament.
b) No one is asking you to watch the replays, so it really doesn't matter how long you think it will take.
c) No one will think any less of you if saving a replay is too much effort and you do not want to partake in the tournament. The great thing about this tournament is that it is free of charge and completely voluntary.
