I loved the commercial for it "We're not in Azeroth anymore."
I'll probably give it a go. How much depth is there to the world?
I have been enjoying the new Azeroth lately though. It was like going back to something very familiar, but much better. It seems so polished from what I remember. Leveling some new alts right now. It's well worth it to me even if I play only 5 or 6 hours a month some months.
