I get it, alliance has been pretty bland for awhile now. Horde allied races are in the same boat though.
Both ally and horde got 2 races that are virtually identical to already existing options (DiD, KTH / HmT, MHO) and another that’s a little more different, but still very similar (MG / ZT).
Ally needs some love, but regarding allied races the blue boys have it better than the red. Void elves are much more appealing than nightborne for example.
