To be fair, I actually support faction-specific queues.
Maybe the server has a max population of 5000, but when no faction may have more than 3000 players logged in at once.
This means when the server is full, there may be no more than a 60/40 imbalance, AND players in the dominant faction are encouraged to take the transfer.
I’d also recommend enabling faction switching from dominant to minority faction on select servers.
