as others have said, pretty sure this was just a one-night thing rather than a bug. i've had fairly quick queues today, even had four av pops - yet i also logged off last night after waiting in a 40+ min queue.
i usually average around 20-30 min for random bgs when i queue on horde at that time, i think it was around the same before i xfer'd from alliance. i've noticed more btag friends playing on their 100s so that's probably why - will be interesting to see if the queues speed up this weekend.
