Ever had to take a trip to Azeroth, but your HS is on cooldown ?
I have a trick for that, because I have it all the time (I am a druid so I respec a lot)
It's not really a dark secret, but not exactly common sense either, in my opinion.
Your results may vary a bit depending on the battlegroup and faction.
1) Queue up for a battleground in Shattrath. AB and EOTS are best, since they are timed and won't last for hours.
2) Use any of the portals to port to the capital of your choice.
3) Now, depending on the queue time for battlegrounds, you have a few minutes to make a ninja-purchase on the AH, or respec, etc. I usually get the "Join battleground" window in about 5 minutes. You have two more minutes after seeing that message before you are ported to the BG.
4) Help out a bit in the BG.
5) When the game is over, you are ported back to the place you signed up, which is Shattrath.
If you have longer queues, you have more time to do stuff in Azeroth.
Hope that eases the traveling pain out there for you non-mages :wave:
