I think if we had only heard new lines from north we wouldn't have disliked it as much. By replacing dinklebot in the old content the end product will be more uniform but it also highlights the differences, and I think it's the differences that make him seem worse. As I've been playing I've noticed that the quality of north is actually better but it takes getting used to. (Don't get me wrong, when I ran the nightfall this week and first heard the new ghost I wanted to stab my eardrums out, but it's grown on me)
