I know, but still. Blizzard has easy options and high elves would've basically shut all of the Alliance players up and I'm pretty sure there'd be no complaints about Horde getting the better end in BfA. I'm not saying they won't happen, but even if they do, it would either come extremely late or would feel like a scam at this point meant to double-juice money out of all those people changing race.
Void elves are the reality though and Blizzard messed up royally by wasting the concept of a possible void class on blood elves, whereas they could've made both a void-based class and given the Alliance high elves(ie blood elves and high elves would have the void class available in the future or whatever).
