Hey Kai,
Again, as i previously said to you on another thread, your mind is already decided so you give the answer and present your arguments in a way to lead the reader in the direction you believe is right. And that is clear when you say "It is not possible".
I will try to be brief, because we both know none of us will change our minds
Here is your genuine feeling. And i know the feeling is shared with many other people.
but there are also other people that feel the opposite.
I believe the answer for a High Elf playable race lies in creating a visually compelling race that resembles the high elf warcraft theme but at the same time differenciates themselves from their family races: Blood Elves and Void Elves.
You said Blood Elves and Void Elves make a contrast like Holy Race vs. Void Race, and it is true. That is the path Blizzard is taking right now.
I also believe that High Elves have also an opposite race, and i have talked about it many times, even in this thread: The Undead High Elves, the ones killed by Arthas and raised in undeath, like Sylvanas. They would be perfect for the counter part. Also High Elf vs. Blood Elf also make sense, since high elves want to return to their homeland but blood elves say they no longer belong there. And void elves vs. undead elves is like the conflict between Alleria and Sylvanas (need to say more?).
I could also discuss the Argus retcon and the relevance of the Silver Covenant in WoW lore, because i don't agree with you on both replies you gave. We have different interpretations, and its ok, and we both know we won't reach a consensus.
