How is the server population?

However, for raiding, you'll be able to group with all of the Aether datacenter which hosts both Balmung and Gilgamesh.

Exactly THIS ^

Because cross world PF doesn't limit your raiding functionality anymore. We also have several players who DO raid, perhaps not quite on the strict schedule that other people may, but this was before The Great Refugee Movement 2017.

Raiders on Mateus did exist before we became preferred. And they do exist now. And even if it's not quite a group you like, you can always go with the cross world PF :3
