This idea is great in theory but when it comes down to it especially during the weekend this will effect the waiting queu to join a server. I still think this is a good idea. but maybe not 1 hour.
I think 30 minutes or even 20 minutes is good enough. With this additional time you can easily go to the bathroom go and get your coffee I think personally it will releave some of the oh no I will be kicked soon have to move fast idea.
