Last night, the WoW Insider arena team stepped into battle for the first time on the arena tournament realms, and it was immediately apparent that things were going to be quite different from our experiences on the tournament test realms.
For starters, there were way fewer people. I also noticed that, contrary to my expectations that everyone shelling out an extra $20 to play here would be a hardcore arena-goer, there were many people on just to have fun. General chat was full of people who didn't know where to go, how to allocate their talent points, and even people who hadn't formed teams yet!
Still, despite the fact the vendor areas had a drastically reduced population, the queues were amazingly short, as Adam points out. Often, I was reading that my team had joined the queue at the same time I was clicking to enter the battle.
