You do love your own head, but it's one thing to have your own perspective it's another thing to drive one through when you are quite clearly shown otherwise, and told otherwise. But then it makes a lot of sense, given your attitude towards high elves.
You have conveinced yourself that blizzard want magic wielding elves only on the horde, and that it's not a thing amongst Night elves, and as such you literally ignore thier lore, ignore what's shwon about them in game, then are dismissive of anyone who points out otherwise to you.

Clearly shown stated in the books WotA and Wolfheart, and shown in game in 1.1, 4.0, 6.0, 7.0 and 8.0 - clear as day infront of your eyes, ancient and modern cities there, arcane wielding night elven groups and legends all there, and certainly playable options , all there. Not even the Darnassian group is druidic, it's priest led with the druids largely concentrated in the cenarion circle.
But keep kidding yourself dude. In your campaign against high elves. You will only end up being very disappointed. The same blizzard who took the alliance high elf and shared it with the horde, and did the same with the Night elf in 8.0, made the blood elf model playable back on the original faction of the race is the same blizzard that will not stop there.
Arcane magic, elven civilization is not the exclusive purview of the horde elves, no matter how much you want it to be, and are excited and happy about it, and want to pretend the rest of the lore of the Night elves is irrelevant or doesn't matter, so you can keep believing what you want to.. Do not mistake the Nightborne going horde as some sort of vindication, if you truly want to see truth, then open your eyes and see what you are refusing to see.
Change your view and interpretation to align with the truth of how things actually are, or you will be bitterly disappointed when things don't go your way.
