So, when you go into the lobby you can click the navigator to go to certain gamemodes. In the new update coming out tomorrow since you have decided to keep some of the old servers a "Legacy Servers". When you click the navigator make it so when it opens it shows all the new servers, then there can be a "Second" page in the bottom right corner that says "Legacy Servers" on it. This would be nice for new and old players to remember.
