I read the response made by Yoshi-P earlier and given time to think it over I'm not really concerned so much now over their plans with Option 4. What I don't agree with though is why they're still making inactive players suffer. Why is it so difficult to let inactive players choose a server too? There's two options:

1.) Make it an option in the SQUARE ENIX Members account page. Upon logging into your account there you can designate which characters inactive or not, will be sent to which server. Give active players first priority on this. Inactive players will be marked as a lower priority meaning that if their choice of server fills up with active players first then they're instead sent to a different server. Or to make it more fair, let them choose up to 3 servers. If their first selection isn't open it defaults to the second. If not that one, to the third. If all 3 are taken, they're defaulted to the least populated server.

2.) Send them to a random default server if one isn't chosen before the date. Upon first reactivating a character and their account, they're then given the option to stay on their currently assigned server, or migrate to a new one providing their chosen server has an opening. This option remains in place indefinitely until they choose and accept a server for each character that's reactivated.

Using the above options it still gives players who are paying right now the higher priority but allows those who aren't playing for whatever reasons to choose a server without being shafted. It's highly unfair that they're pulling this stunt, and personally I believe it may be influenced as an incentive for people to start paying right now.
