Have you ever considered that some people may have genuinely enjoyed vanilla?
I have no doubt that there are people out there who remember Vanilla World of Warcraft for how it really was, who can list all Vanilla gameplay systems and features in exact detail, and who still prefer the game as it was back then despite all the progress and additions that have happened since. These people would certainly enjoy playing the Vanilla game if they could, and I can understand if it is frustrating for these people to be placed into the same group as those people who actually are nostalgic.
The thing is though, that there are a lot more people who are nostalgic than people who are not. Those people who are nostalgic have some great memories of fun times they had back when the game was new and when they were playing with their first characters in their first guilds. But often these people are treasuring their good memories, while at the same time forgetting (or downplaying)
the not so great things from back then. If they could play Vanilla today, they would most likely not find the same level of fun they had back when they were new to the game, and they would most likely be annoyed by the lack of many of the quality-of-life improvements that have been added to the game since then.
Whether or not people are nostalgic is certainly something that there are a lot of different opinions on, and we fully acknowledge and appreciate that. That being said however (and I know this may come across as being harsh or dismissing to some)
, the developers have the final word in the end. Their preference currently is to keep the game moving forward, and this means that their philosophy is to keep evolving and expanding the World of Warcraft universe - supporting old versions of the game does not fit well with that philosophy.
