Guess what, Mat… your suggestion has its own huge slew of community problems.
Just as an example, anyone planning to move would have to plan on not making friends on their initial server. They’d also have to completely reroll their character, and depending how long it takes for queues to start appearing, they might have put too much work in to want to do that.
So what then? Paid server transfers? I don’t think so; people around here also blame character services for the downfall of retail. Everyone with a #NoChanges T-shirt would be appalled, horrified, and made brutally angry by such a thing.
