Well, people can glean info through process of inference. I was on an Alliance heavy server. Cross-realm BGs didn't come out yet. There was one Alliance premade that ran 16 hrs/day, and one Horde premade that did the same. These were the r14 groups. Alliance did not have instant queues. Horde, on the other hand, did have instant queues. It's not difficult to put 1+1 together how the BG scene on the server could have been given those facts. It doesn't take a rocket scientist to figure it out...
