I don't think they've decided to not make solo content anymore. I think they just finally decided to make group content, and I for one am grateful. This game is easily the most solo friendly game I've ever seen. They even provide a single player mode lol! The thing this game is lacking (and in no small way) is group content. In order to provide that in a meaningful way, they have to balance skills that are over performing. If they just bring everyone up, then they're just making more solo content.
