As much as horde vs alliance is the underlying theme of the whole game, Blizzard clearly favor orcs vs humans. The game is way too narrow regarding the presence of other races in Azeroth or wherever the story is located. They need to give other races some love, and show that each faction is composed of several races. It is so boring and repetitive to always find the next hub to be orc-themed for horde players and human-themed for allies.
I main an undead, and as much as the undead are a part of the horde, I don't play it for the sake of them being horde, but rather because I like their looks, theme, architecture, etc. Now they are basically wiped off the maps, and it wouldn't surprise me if Blizzard built Orgrimmar 2 in the ruins of Undercity.
If Blizzard wants all the other races of the alliance and horde to feel some connection to their faction, then they better make them visible by having some hubs be themed with race specific buildings of races other than humans and orcs. Just placing a blood elf in an orc building isn't enough.
With the new warfront thing or whatever it turns out to be, it would make sense to make the horde's hub undead-themed or maybe even blood elf-themed, considering it is in Arathi Highlands. All I see is more and more humans and orcs.
