Ah but there is no difference between choosing for the love of a name or a number.
I have said this before earlier; Server 1 and 2 will fill up first. Server 4 might bewill beavoided by Japanese people for superstition or loved for the culture of it all, server 10 has officially been offered as a specific language server and you can see groups popping up claiming server numbers for thier servers (7rabia, 8esaid etc)
Even then, they might release exp loss on deaths next month and of course there is a reason, doesn't mean everyone in the FF world should say ... oh ok if you think that is best.
