I'm inclined to believe they've resolved to just leave it closed until the server shuffle at least. Possibly until 5.0.

I know quite a few jimmies have been rustled in the raiding community about it, particularly on Balmung, so with the move to Crystal, I can see a lot of people jumping ship to other servers on Aether. Hell, I'm 99% sure most of my FC is, I've already been working with some of their alts to get a foundation laid down on Midgard.

When Serverpocalypse 2019 happens, I anticipate a noticeable dip in Balmung's population, at which point they might take it off congested status.
