Doesn’t matter. His standpoint makes sense, and he said the team collectively felt that way. “We felt” were his words. You can try and strawman that away, but that remains true considering the Alliance didn’t get Nightborne, the Alliance didn’t get HMT, and the Alliance aren’t getting blood elves. Multiple points where neutral races would have worked and the Allianced begged for it to be the case - and it didn’t happen. And it shouldn’t happen, mind you.
Kul Tirans and Humans are the same race, and yet both are different playable options. The fact that High Elves and Blood Elves are the same biological race is irrelevant.
