I understand that the removal of maps and the adding of S&S really made it easier for the development team. Maps did mess up a lot of code and were all around gross to work with. However, because of their removal many things have changed. It's just not the same feeling of opening slopes, and skiing to the bottom. Or building a "parkour game" in the bedroom. I understand this "terrain" can be accomplished with bricks, but it's just not the same. They aren't smooth, and are rather a hassle to download and ghost.
I understand that Badspot and the other put a ton of work into this update, and that it must be really discouraging to hear all of the drama towards your update. People just miss what used to be, and I guess they just have to put it behind them and think about the upsides of the new system.
