I'm sorry but allowing queues at all is not acceptable. You have a great game, but I disagree with your solution for handling eventual player loss on servers. I will be very surprised if your 'solution' has any effect in the long term of inevitable player loss on servers. The day will come sooner or later where you will have to merge servers. Delaying that using this method is not the answer, because you are punishing people who only have an hour or two to play each day by forcing them to wait 25%+ of that time in a queue.
I like the game a lot, but I am unsure if I like it enough to spend 25% of my play time sitting in a queue. You had best think about because I would rather play a lesser game if it means I actually get to play instead of posting my dissatisfaction of matters on a forum when as a paying customer I should be in the game enjoying myself with my friends.
