I bought the Expansion two days ago and I started over with a Witch Doctor. There are so many changes that I felt like starting again to get the grasp. There's also this ... Season thing to learn about. I'll reserve judgment to see whether I buy the Necromancer pack, because I need to feel like playing it long enough to evolve other heroes.
And I also learned that I have Starcraft 2 bound to my account. Which is odd, because I don't remember buying it, although I remember considering it.
