2002 completely a problem with the game itself?

But why is this necessary? If you're already in the login server, why are you being made to disconnect and reconnect again? From my perspective, that makes absolutely zero sense.

It is completely unnecessary for a properly implemented queuing system you are correct indeed.

Thinking more about it (and I wish I was not) it may be;
A.) Legacy code designed to accommodate issue that no longer exists.
B.) Code designed to accommodate currently existing issue with how the server and client resolve handshake requests.
C.) Something I am not considering from being out of practice or not coding in such ways as it is stoopid.

Actually it is worse then unnecessary. I made post in other threads about this.. Each time a client is booted with 2002 it must re-do the entire process of logging in and re-entering the queue which as may guess pings not only login server, but character database and queue server. Knowing it does this every 15 minutes boggles the mind.
