SE has always tried to balance servers out. Even in FFXI they did it, except you never saw it... because you didn't have a choice of server... UNLESS you had a world pass from a friend who was already playing...

Sorry SE you should have stuck with that system, people could have made characters been placed wherever, and not been any wiser that there was a lock unless a friend was unable to buy a world pass.

What you created was a list of these servers everyone gets to look at but can't play on, and most feel they should have access to all of them no matter how full they are.

There are many ways to manage your game population, and your original system was probably the best and that system was 10 years old.
