Cuse Void Elves lore is going to be developed on BfA, the first itineration of BfA is "Faction War" and as how the Blood Elves demonstrated Garrosh their loyalties, Void elves are going to do the same with Alleria opening void portals and hundreds of void elves appearing and impressing the faction leaders. People cry about Void Elves not having Lore its because they are a "pre-ordered" benefit of BfA, heck we shouldnt be even playing them thats why they make no sense, they lore is vague yarada yarada. Hopes come on the second itineration of BfA (second raid, prob old gods and void lords) wich oh "void elves are actually void creatures" for me thats tons of future lore.
Yes we get it you want Legolas, sorry about that. But Horde is waiting for you.... we have High Elves ass everyday ;3
