I'm not convinced any of the Allied races are that great - but that's why they're Allied races and not new races. They're effectively a bit of added customisation to existing art that, in two cases, lets one faction play a "member" of the opposite one.
And I'm cool with that. Some people will really like the new options, which is good for them, while others will level them for the Heritage Armour.
I can't see a single valid reason to complain, really. Not one.
