Tbh, night elves and blood elves are the most fitting for mages lorewise. It's more the fact that the Highborne are the reason the Night Elves are what they are today. Before that and before the sundering they didn't call themselves that and didn't have these exact creeds and beliefs. So the conflict with the Highborne really created the situation and the NIght Elves that are today.
But it's gonna be quite fun to see the lore around it.
