I understand the frustration with the grind. I'm so over those bottle neck orange items that are still needed as Cyan continues.
But your concern about the seemingly endless grind is an item GS have brought up in our meetings time and time again. The good news is that Gree has listened. They may not announce every time, but we will see ndd days come along more often to help ease this. I don't know how often and I don't see Gree doing something along the lines of combining ndd's into 3x or 4x drops. More frequent ndd's is not as optimal as adjusting drops in each chapter, but for the time being it's something for the short term.
