I'm not sure I know what you mean, but I'll try to explain myself a little better. Take for example Neverreap and the Fractal. Many people are burnt out on those two dungeons right now, but what if in the next patch they were a good way to get some of the best gear? Many would be frustrated about that, because it would seem like just yesterday that they were in those dungeons every day and now they would have to go again.
If the Crystal Tower weekly dungeon were upgraded to drop Gobdrip, it would frustrate me because I would feel obligated to run them again because they are an efficient way to gear up, but it seems like just yesterday I was running them over and over.
