I believe there’ll be separate leaderboards? So, the ones on Aether won’t be affected. I may be wrong, but that’s how I interpret it, like with Oasis and Aztec on Skyblock.
No one is forcing these players to switch to the new Olympus server? If they’re content with the community and the current economy there, they are more than welcome to stay there.
The way I see it as; More players will get to experience Olympus. Whether that’s on Atlas or Aether, is completely up to them. The servers will be entirely separate (as Dacon mentioned), so players won’t be affected if they decide to stay on Aether. Of course it’s a great opportunity for not only players who may be struggling in the economy on “Aether” (Olympus as of now), or new players to the server, they’ll get an entirely fresh start, and won’t find it hard to compete with players like Arenzo who have achieved several hundred rebirths, and will actually have a shot at getting on a leaderboard.
