There is more than one server. Just instead of limiting people to a single shard to play on everyone has access to all of them.
Think of it like WoW (Dont shoot me for mentioning WoW) but where instead of your characters are on one server, you can log into the character and then your put on one of the servers randomly.
but like I said... I have no issues with their being a queue only that if fails 98% of time because your constantly kicked back to log in screen before you get through it and are then put back at the end of the queue.
