Hi all,
This is very circumstantial, but i should imagine a lot of people leveled here in AV. In doing so you probably did not pick up your Stormpike Insignia like i had not. I just went there to hand in an AV victory quest for 50k exp and noticed that i could pick up my Insignia. I was then allowed to upgrade my insignia through 6 Quests. Each one giving lots of Iron Forge rep, Guild rep and around 260k exp. Not bad for 5 min work. Not ground breaking I know. But its something you may of missed.
