We have attempted rotation servers on more than one occasion. Each one of those instances resulted in failure because much of our regular player base did not fill the servers. It's great that you guys yourselves would like to help, but it needs more than that. We need the heavy hitters who play DoD every night to also help out.
The problem is, and was in the past too, that most of those "heavy hitters" ... the people with the most play time, limit their play to one or two maps entirely, and historically have refused to play elsewhere. This refusal to play or learn new maps is what caused our rotation servers to fail, and would likely do so again. It's sad, but it's happened twice now....
