The Alliance has always been all about the light, if anything Void Elves only hurt the classic Alliance identity. My main issue with them though is that every single thing we’ve seen them do could’ve been done by a generic mage. Making portals? Wow, haven’t seen that done before. Reanimating corpses to terrorize the enemy? May as well have just brought a DK
I have yet to see Void Elves do anything that is actually new, y’know?
