Before people are all like: Omg, why you changing things TimeLady?!?!?!
soah had great success running the schedule like this back in 2009.
It also allows people more flexibility and creativity in the types of games that are run, so if someone wants to run a sort of "semi vanilla" game, they can, instead of being pigeonholed
The hope is that there is a greater variety of types of games run, be it anonymous games, lost wolf games, mason games, small double wolf team games, etc etc, as opposed to small variants on the three main categories of ww.
That, and it allows more flexibility of when to run games. For example, we can run a slow game and a mish mash on the same day, because it's unlikely one will take the player pool of another. And if a game doesn't fill one slot, it can be rescheduled a lot quicker
