Well, I broke down and picked it up the other day. I gotta say that so far I am impressed with the overall design. The hero creator is excellent! I.'ve spent almost as much time making up heros as I have in game.
I do like being able to make some sort of progress in an hour or so of play, but I'm still only level 7 and I'm sure the leveling will scale up soon. We'll see how it fares after the first month is up.
