I will never understand why they thought people would be playing this game in big groups of friends wanting to play together, as this was often touted as the reason they don't want to put in any restrictions on server choice.
If a servers population is already more than 52% (which for arguments sake on a server with 5k accounts is still a margin of over 100 players) in favour of one faction they should simply have made it impossible to roll that faction on that server until the balance is redressed. Mechanics like that from the moment the server is created prevent the dumb snowball effect once the imbalance hits around 60%.
But apparently that would stop the guilds of players transferring over from other games or w/e the hell they think happens being able to play together.
