I guess I'm a double sucker. I bought it for the Xbox One, thinking it would transfer over to the 360, then realized it goes the other way, and had to purchase it again. And yes I did call M$ and try to get it all sorted out, but they just said, WAH, WAH... don't be such a dumb ass next time, and thanks for your money.
Anyhow, I'm not disappointed in the DLC, well worth the coin. And stuff always gets nerf'd, that's just a given. The thing is if you don't want something to be nerf'd, speak up while the dialogue is active, because they seem to listen to their customers, and if more people present a better argument for the nerf, then against it, it's not hard to guess what's going to happen. Not enough people spoke out against the GT nerf, so it got nerf'd, that's just the way it works.
