Since there is a problem with the server being overloaded on Thursdays, why not change the weekly schedule for the launch leagues?
Have the launch league's games due on Saturday's with the new week of play beginning on Mondays. I'm sure this would help the overloading problem be seperating the perpetual and launch leagues play times.
If this isn't possible, at least move one of the league's start day to wednesday or friday.

just my 2 cents.
