I brought this up in another thread:
As such, we’ll be instituting a temporary measure that will log all characters out simultaneously across
all Worlds on a data center once a day.
Reading comprehension dictates that "a" is akin to "one," therefore you can read it to say "all worlds on one data center." It's no mystery which server is actually having the issue. It's Balmung. The data center it is located on is Aether. Aether will most likely be the only data center, and its worlds, experiencing this lovely addition:
Adamantoise
Balmung
Cactuar
Coeurl
Faerie
Gilgamesh
Goblin
Jenova
Mateus <-- I really feel for these guys
Midgardsormr
Sargatanas
Siren
Zalera
Really, at this point, I'm all for splintering Balmung. I'm pretty sure the transfer incentives are there so SE doesn't start enforcing a hardcap on the server, but with these issues, this should be done. It'll happen again come 5.0. Even if they never remove the ability to transfer to, or create a new character on Balmung, those returning to the game will cause this to repeat. Until players are forcibly removed from this overpopulated server, because not enough are taking the incentives, the issue will happen again. That's not doomsaying, that is just a fact.
