I guarantee if Aether is opened up to new characters/character transfers at any point in this expansion, they are going to get an unprecedented number of people wanting to have their characters on Aether. Why have your home world be anywhere else at this point? If you're on Aether, you're as free as a bird. You can go practically anywhere you want, anytime you want. If you're on any other data center, good luck getting into Aether, and god help you if you need to do any sort of content (like Diadem) that forces you to be on your home data center. If you're not on Aether, you're a second-class citizen.

To be honest, I'm not sure I have much faith in them rolling things back at this point, and if Aether does open up, I'm seriously considering transferring my character over. If this is really how they want things to be, fine. You reap what you sow, Square Enix. Enjoy Aether becoming even more densely populated and exacerbating the problems even further, I guess.
