I did have some fun talking to NPCs I haven't talked with in a long time, and found some new quests that I didn't know about. So, indirectly, it had little bonus.
I really miss the outlying NPCs that used to out in beta. There were some scattered around the world out in the boonies, like in the ice corridor between Augh and Kira, and on the ice floe north of Mahagra. It would have been even cooler if the further out you searched, the more and greater value candy you get.
Also, none of the Festival NPCs will give you hard candy for trick-or-treating. Only special mob drops and old NPCs on my list above will have a chance of dropping hard candy, which is required fuel for the skeleton costumes.
