It is still possible to queue for a specific battleground number if it is the call to arms for it.
E.g If it is AV weekend, talk to a Stormpike Emissary walking about the cities, and you will able to queue for any of the already open AV's. (Normal Battlemasters do not allow you to set which BG number you queue for anymore.)
Why is this helpful?: Well now you dont have to sit through a full AV to complete the daily. If you select one of the already up servers, you will be enterned near the end.
Its also great for AV weekend lvling, just keep adding to these and collect win/loss XP every 5mins, since AV tends to last all 600 resources at levels less than 80(So games take 30+ mins).
Sorry that this may seem useless to some of you, or not even make sense. Found it hard to explain with my poor english.
