Oh, and I also met Kalgan, who gave some pretty interesting information, albeit was very careful not to spill any secret information. I found out from him that rated BGs were planned and that we would hear much more about it at Blizzcon, but I did get to find out that Blizzard intends to make rated BGs a lower "echelon" (or "tier") than arena and would be an alternative way to get gear. The way I took it from Kalgan, Blizzard intends to allow individual players to pug queue rated BGs and every player would have their own PR.
