The argument associated with this is simple: why only one player's classic greatness can be different from another player. Who is the designer of Blizzard who said that the old features of each player are good or bad? This is a way to show that Blizzard believes (at least to some extent) that World of Warcraft belongs not only to its creators but also to its fans. The struggle between the author's intentions or the game design orthodoxy and "the player is absolutely correct" is at the heart of the contemporary controversy of countless games. But so far, Blizzard seems to be focusing on its plans for WoW Classic.
In fact, it has now been promised that modern World of Warcraft players want to test and report what seems to be wrong today, but what we really wanted 13 years ago. Blizzard has publicly released a known non-problem directory, known as the "WOW Classic Boosting" is not a "bug" list, which has become a common phenomenon. For example, the batter of the Tauren athlete competition is more complicated than other games. In modern games, this can be considered a serious balancing problem (see: Apex Legends). But this is what Vanilla World of Warcraft looks like, so it is faithfully reproduced.
Even some products look more like errors than anything. For example, from your notes:
NPCs that provide multiple tasks may inconsistently display that they are a point or even a "!" list of available tasks. They were inconsistent in 1.12, and we reproduce their complete inconsistency at the time.
Some players are actually surprised by these obvious flaws - even players who are really eager to see World of Warcraft release will rely on the memories of Vanilla Warcraft. In fact, it may have been a long time since World of Warcraft was first released, and the player's memory may not always be accurate. Some details may be fresh, but other details may soon be lost, and those missing details may allow players to revisit the main experience of WoW Classic.
Blizzard Community Manager Kaviax hints at this in a post on the WoW Classic forum, including a list of non-issues they know, writing:
As we discussed earlier, Warcraft Classic sometimes brings different memories to a wide variety of players, which leads to a misunderstanding of a few about what is or is not expected to be used.
Most people who have played multiplayer games for many years will tell you that the first game you play has something special - World of Warcraft is the first of many. You can become so popular in the uniqueness of the first experience, you ignore many flaws. Many people may see the WoW Classic with rose glasses, and many people just forget when they added what features. Some of the Warcraft players today may be too young to even play Vanilla World of Warcraft.
Not to mention that everyone has an unrealistic view of Vanilla World of Warcraft items. Many people in the WoW Classic forum have said that perceptual error is just the entertainment of the first game. As mentioned earlier, individual player defects are often a key component of the main positive experience of an alternative. WoW, will definitely make many purists happy. But this shows that WOW Classic Boosting for those who have fond memories of the game around 2006, this is definitely not the case.
For some people, those memories are just those memories, because they are found to be imperfect.
