Continuity error with game lore

Hi,


So, Void elves were originally blood elves. Seeing as how this is from the game itself... wouldn't it stand that they would be able to also speak/understand orcish? What's up with that blizz? Why can't I talk to horde on my Velf? They were banished from silvermoon yes, but they WERE a horde race to start with, that did understand orcish. HOW is it that they can't do that anymore?



Please help.

I didn't find the right solution from the Internet.
