We're watching the populations, watching how many are transferring, considering the impact of those transfers, and working to ensure destination servers have a healthy population. All of this data informs what we open up and where those servers go. It's important that we let the data we're receiving guide the process, and we appreciate everyone's understanding.
Perhaps would it be possible for you to let us in on some of the things you are considering when making the decision. I think people would be more comfortable knowing the pieces/decisions that you have to juggle to make it all work. They might be still unhappy about being some of the last, but at least they would have some insight as to why it takes so long.
