Out of curiosity, how would one apply to this weekend only group? Also what is to stop the person who will go on every day from joining this division in order that they may win?

I like the idea. I don't see why you shouldn't be able to play both, even if you do play everyday, as long as you cap the energy REALLY high like Cire suggested at 5,000 so you don't need to play everyday not to miss any rehearsal. But I think you'd need to take the staff idea out of the same or modify it a lot otherwise it would be the same old story. Groups that have been around longer, made the most money, and bought the most staff will always win.

You should only be able to do one. Div 1-3 or DCA

It is a good idea I personally would play the old version but all my friends who joined at the same time as me have basically stopped due to the fact they don't have time to go online.

The DCA thing would be very interesting to see...
