i would gladly gas the whole Dalaran if the leader of Kirin Tor is jaina.
as i remember inside the Void rift while you are Rin'Dorei i saw some high elves over there Consume the void thus becoming Void elves
High elves will not gonna be a thing in near future and i hope not in the far future as long Both Faction still exist.
It's pretty clear he didn't end it though, based on most of the reactions. You still have the same people posting the same arguments that his response didn't address. You aren't going to convince everyone, there will clearly be people who will never accept an answer if it's not the one they want, but you can address people's concerns with it and turn them down in a way that will get the huge amount of whining to stop. Like I said before though, it's a perfect answer for gloating and trolling.
It isn't more elves, it is being able to play the ones we can clearly see representing the Alliance on multiple occasions.
Would I play one? No I prefer human. I have a Blood Elf and tried a Void Elf in Alpha (forced to reroll due to the Heart of Azeroth change prior to the Beta wipe), and if my Blood Elf had that nice of a beard I might like it better. The principle of the matter is that High Elves exist in the Alliance and they are represented heavily enough that people want to play as them, and have for well over a decade now. You can't play as a Blood Elf and represent the Alliance, nor can you look like a High Elf as a Void Elf. That shouldn't be difficult to understand. People want to play what they see, and they see High Elves, in the Alliance, repeatedly.
