Bg queues.

I don't want to open another debate about this subject (always more pvp on alliance side, etc). But I would appreciate some information.

What faction has the shortest bg queues (to enter). A player who likes to come online and enter bg, quickly, maybe with 1 or 2 friends. Should he/she join the horde or alliance side?

Does it depend of server time, or will there always be more alliance, for example (or horde)? What's your opinion? What faction does need more people to go into bgs?

I'm not talking about which faction wins most bgs, but the one with the shortest bg queues. I have tried characters from the horde and alliance side, and sometimes it took more or less in both factions.

Hordes get pretty much insta Q.
