I always use Singapore servers.
Singapore’s performance is lower than that of US servers. If the number of people increases, you will be late to play.
If the user can create the server, there is no problem with the lag, but it is not possible.
So I propose a system that supports servers.
The user suggests a country in which to create the server.
If a developer can get a server, ask customers to raise money.
Once you have the money you need, create the server.
Thank you very much.
