The current que system, which just tries to connect to the server every x seconds isn't helping anyone, it just lessens chances to get into the server. I'm better of with just clicking like before.

So, my idea is as follows:
A real-time que-list, much like poker clients have. If you want to join a server, you just join a que and when a slot gets free, the first person in the list gets to join.

There should be some limits of to how many server que's one can join etc.
