What's a new RP server going to do? Hypothetically it would just run into the same problem Balmung does. It'd be the only RP server, and eventually it'd flood so much due to increasing population that it would have to be locked down. ( If people wanted to even move, I doubt a massive flux of players would transfer from balmung to it unless the incentives were huge just due to already being established here with the community of RPers and Non-RPers )

As someone else said, if there's going to be designations on servers, it needs to be done at launch, and there needs to be more than one. As it is right now, the only real solutions is for them to increase their hardware tech, because lets face it, they struggle with things even F2P games can pull off fine enough, or just deal with one of the alternative unnofficial RP servers until it opens back up. We'll probably see /some/ but not a ton of migration from balmung to the designated servers so there will be openings.
