I had tons of fun watching the Brawler's Guild invites get sold tonight in what I will call a total "gold annihilating" bid war. It was like a "WoW Millionaires Party" in the room - Jeweled Onyx Panthers, Yaks, all the expensive mounts, and all the gold makers bidding against each other.
Day 1 Final counts on Drenden are as follows, in order of auctions ending....
...went to bed, but it was at 44k (Medium)
The first three (135k, 121k, and 150k) shot up from the 35-45k range to their final amounts in a massive bidding war that went on for about an hour. it was more fun watching than I think winning. And sadly, being "first" means nothing because there is no way to prove it. The achievement only shows the date, so the best thing you can prove is that you were one of the first TEN to get one, but that's it.
No, I did not win one, but I stopped bidding very early in the day, not worth that much gold to me.
