Mostly, I sat in line.
I logged in, discovered that the new areas were swamped, and stayed on Neve.
Shadowmoon was empty.
So were the BC instance queues.
I figured that there ought to be more people like me who felt that the new level areas could wait while the people rushing to get to L85 finished, but I didn't guess at how few people there would be. The line for a BC instance --even with the new battlegroup combinations-- was 30 minutes minimum. This was well up from 5-6 minutes that was in place a day ago.
Therefore, I made certain that I did a few quests to creep closer to L70.
Oh, and I created a Goblin Rogue, named Jíg after the main character in Goblin Quest. (Sheesh. Someone already named a Goblin 'Jig' by 5:00 AM EST. Jim C. Hines would be so proud.)
What did you do on your first day?
EtA: Amusing moment of the day: Curiosities and Moore is now a consignment shop.
