A single thread with very few people that were reminded of an event saying they were fond or didn't hate something doesn't really count for much. When you get that close to zero, well it counts as zero. In fairness they have been morphed into other things, islands in BFA for example are a spin off of sorts. The biggest issue with the MoP version they didn't solve any problems, achieve any real goals, were moved away from almost immediately and with that fade away like Ruby Sanctum or other forgotten parts of the game that were lack luster and brief so it is as if they never were. As much as people may want to argue they were a success or had any real following, if they did they wouldn't have gone away and we would have been talking about it a lot more from then to now.
