It's lacking greatly...
I don't get it. They keep whining about how its easier to make allied races for the Horde, yet they came up with (asspull) Vulpera out of nowhere. They can do the same for Alliance, but don't seem to do it...
I love Lightforged Draenei, but they are also very lazy... More could've been added.
But yeah, the same can be said for Highmountain.
I just hope for them to tweek the Mechagnomes a bit more. Right now it's not enough for me personally.
