I played the game at the beginning of the year, it was OK, I'm glad I missed it at its worst. But, I don't think I will buy the DLC, maybe if it gets a significant discount for one of the Holiday Sales.
That being said, 2.0 sounds like it's going to fix the game in a lot of ways, basically making the game what it should have been from the start, I might start a new game if the reviews of the 2.0 system are really good.
