First of all, I can know the reason Blizzard eventually require to allow the Fresh Server to have transfer to or from other servers. The Fresh Servers at some point will function as the other servers. What time frame will it take? I'm not certain. But , knowing that it is likely to happen, I can understand needing to keep Fresh Servers linked through transfers to all the other servers.

Not having any transfer, I do not believe is the correct solution. When the server has reached the threshold of being as other servers and the transfer doesn't function it will slowly end up dying. It won't attract many new players. Why would you want to play on an Fresh Server which is locked in its own world, when it's no anymore "Fresh"?

While I believe that the Fresh Server will be home to an adequate number of players, I doubt it will have the amount of players as the massive servers are currently in use. Over time, players end up leaving the game. If the server isn't receiving new players or transfers and aren't allowed to transfer back to the server to replace the players, it will slowly die as time passes.

The transfer of server data within 90 days of the date will make Fresh Servers to be regular servers in a shorter timeframe than in the case of being left to themselves. In addition, I am convinced that once the transfers have been completed then they will be closed and the Fresh Server will cease to exist. The majority of transfers that go towards the Fresh Server will just be players moving alts with the gold they gained when playing Classic or TBC. I doubt it will attract many new players, only those who transfer alts. However, I can see a scenario that has a lot of people simply leave their current server. Fresh Server.

After that, the motive to play on a fresh server is no longer a factor. The players will go back to their previous servers, where they might have friends as well as their wow tbc classic gold and alts that they obtained from Classic/TBC. It's not even including those who will simply out quit because the server is no any longer fresh. All that will do is result in a chain reaction of players leaving to play on a different popularity server.

One way to can see the Fresh Server lasting long-term is if they allow transfers to it in a more extended period of time than what they are currently planning. What is the ideal timeframe to allow transfers? 180 days? A year? Longer? I'm not sure. But at some point, Fresh Server will need transfers. Fresh Server will need to transfer to stay alive.

I am aware of the Blizzard reasons for transferring into an Fresh Server. Servers can die if they don't opens after 90 days. However, If they're never open, they'll simply die slowly. My guess is to be somewhere in middle.
