You lose a thriving economy.
You have no guarantees that the server will be successful.
FATEs will suffer.
Crafted and gathered items don't sell as well.
Aforementioned items sell for a lot less.
Players will choose to stay behind and tear your FC apart.
Confusion as to which server you officially are on after leaving.
