While I'm excited for a lot of the stuff coming. Story I think has been the most lacking content. Over a year in and Makeb is the first true advancement of class stories. You don't necessarily need to raise the level cap to do that even. It would be nice to see the class stories progress a bit faster.
Actually, it isn't. There is no individual class stories here. It's just another planet with another planetary story arc. Your class story will remain at Chapter 3, even though they're referring to the story content in this "expansion" as Chapter 4.
