Why is this "But because Alleria is a High elf....now all the rest of the Void elves are now High elves..." crap sounds so wrong?. Simple, because the "Void elves" we use used to be Blood elves, now turned into "Void elves".
So nop, those are not High elves. The High Elves are those who are stranded in Outland, Hinterlands, Loch modan, etc...Those few. Those ARE High elves
Why are you giving Void elves, High elf features, if they are not even High elves?. They used to be Blood elves, but not anymore. They turned forever into purple elves.
