This is not really an issue. Maps can be selected from a pool. (Preferebly some good custom maps are included.) And in my personal experience the Jagd/Ele/ISU meta haven't been around the last couple of months.
There are strategies around it.
The problem with a ladder is you can't just say: Here is a ladder, sign up and play against each other. The persons organizing needs to keep constant pressure on people and help people who are passive get games, else it will die down quickly. As well as come up with incentives to get people excited about it.
That was basically why ogl died out. Teams got complacent. I can see why this idea is fizzling out, just like my tasty fresca.
What if we tried a featured 4v4-game every sunday night?, casted live, community involvement?
