The only time I've seen a queue for ARR was during early access (I think). I'm pretty sure I was between 600-700 in queue, but it only took about 5-10 minutes to get in. I agree that a queue of 1000 would certainly help things, but I admit that I have no idea what enabling a queue system does to the overall server load. If it doesn't do much, I think it should be turned on permanently.
