I'm quoting this from the managers thread, so maybe we could have more opinions on the subject.
Anyway I think it unlikely to change midseason, but we should definitely discuss it for 2011, so let it be in this thread as a reminder.
The reason behind starting on mondays, is that on regular tourneys, if the start is sunday, there are only 2-4 matches.
On GS, sunday start has at least 1/4 of matches, which is a lot.
I don't see any reason why the games hasn't started today.
I suggest for future GS not to skip that day.
My opinion - the other reason we start on Mondays is, beside the fact that there are usually only a couple of matches scheduled for Sunday, players tend to forget to post picks during weekend.
To me it has happened a bunch of times that I'm late for Sunday start tournaments for other games, so that's why I'd vote yes
to always Monday start
