Ever since nightborne added the nigh elf animation to the horde, and void elves were weaved out of nothing, I do not think that will remain an argument for a long time.
Depends. For example, the events of the 4th War could’ve been presented as some races who were not sure about their allegiance now making a choice to drift away from the horde.
Or if the devs would want to be “morally grey”, even though I am not sure they have the people in the narrative team to pull it off, they could show that while the leaders do buy the idea of “it was all Sylvanas”, the “common folks” could be more in the “I’m not sure about it” camp.
Both could be impactful in the context of what happened in BfA (leaving aside my opinion that the events of the expansion were poorly chosen and badly handled).
When it comes to the old lore, there is always (more or less) a way IMO. For example, the horde branch of the high elves could focus on finding a new path, exploring more of their “eternal sun” believes / ideas, have more about commonalities with nightborne with both races being a catalyst for each other to learn more and move into the shared future.
On the alliance side though, the story could go in a direction of “comming in to peace / understanding the past”. There are statues that depict elves as high elves (dancing elf statues) in the Well of Eternity dungeon and Tomb of Sargeras, even though at the time high elves should not even exist. So, there is more to reseach about, for example, why high elves had Sanctum of the Moon

So, there are ways to look into the same history from different perspectives or for different goals IMO.
To me it feels like the usual “solving the problems the players do not have by tools the players do not want”. I do not think the players wanted to get “kind of but not really high elves” and that the race with next to 0 backstory as is a valid alternative for something so requested.
I am sure they recognized some opportunities behind it. But commercial software is not a dance for 1 person. It’s not enough for the devs to focus on their likes or dislikes.
By chasing their vision they left questions and some disappointment. Hardly unexpected. The question only is if the devs will still consider their view of how the game should be developed as a good one, or they learned something in the process.
That’s where it all started. And the reason for me linking it is because a lot of players believe that
Hence having high elves avaliable to the alliance would not be a reason for the players to leave the horde, thus it’s safe for the “identity of the horde” if there is left any after what the devs did in the WoD+ time frame.
