So early on Saturday and Sunday I was working hard for exhalted in AV and starting the long road to AB/WSG faction so I signed up for every battle ground then chose the one I wanted.
Of course I immediatley hopped into AV when it opened. Imagine my disappointment when the message "This battleground will close in 5 minutes came up". The 6 or 8 of us in AV quickly ran north to get the SH bunker, hoping more would join. Alas, the game ended and then I got the same reward I would have gotten if we would have lost: 125 faction for paying, 12 (maybe 6) per battleground and a token.
Now I’m on a loosing server so getting rewarded in AV so quickly was a JOY.
So my theory is that blizzard has a minimum of signups before it opens a battleground. Once the # of signups has been reached it offers each person the opportunity to join. The battle ground is committed to opening at this point. So if only 2 for WSG or 4 for AB or 10 for AV (example numbers) show up then Blizzard has to close the BG and gives everyone a thanks for playing.
I know you know this already. So why do you care? Because with a little planning you could get 150 av faction in 7 minutes. Do it 3 times and you got a set of tokens.
Here is a detailed plan of how to get quick AV faction:
1) You need to be on the less populated side of a server (most the times that is horde)
2) You need some accomplices to make this work. For WSG I think you need at least 5 people to start the game, for AB it is 7(?), for AV it might be 20.
3) You need all of you accomplices to join the queue early in the morning.
4) You need to hope the "other side" is lined up chomping at the bit to beat you down in your chose battleground
5) You need 1/2 of your accomplices not to join the BG or to drop out immediately.
6) You need to hang out in the BG for 5 minutes and hope it doesnt get busy.
And there you go!
