I mean, we already did know that the WoW developement team largely ignored the actual lore of the game.
What is said in this “real interview” would not be a huge surprise to me.
It is a shame that we can not get a fixed lore, it tends to tell a better story when writers actually have to creatively maneuver their way around. Is it a challenge? Definitely - but overcoming it is the mark of a good storyteller.
