Yes. But you are talking about just a few teams. On each server there are thousands of matches per day, ranging in times from 9am til after midnight. To start all these matches at the same time would be a huge problem. And in any case, I can't see what difference staggered ko's makes. In real life, same time ko's are to stop teams stage managing results. But on here, the match results are out of our hands, so the "cheating" aspect doesn't come into play.
