It would be nice, then I think we'd be able to make new characters. Even though we should be able to make characters on the closed servers since Yoshi himself said that one account having 8 characters on the same server wouldn't matter since only one of said character can log in at a time lol.

But I think at least people who come back from the welcome back program can play on the server they were sent to during the merge otherwise it be pretty bad if they set this up and some chars were still in limbo XD.
