Ah yes, I remember the countless threads of Horde players saying "I want me some more of that AU stuff, who doesn't like AU" or asking for Tauren but with antlers.
It suggests no such thing. There's literally no data here that would do so.
Yet looking at those numbers, Void Elves are the superior option to Nightborne. So that would be at least two. The rest of your post is subjective nonsense.
Mok'nathal? Nope, AU abominations.
Forest Trolls? Nope, Trolls whose model is at least partially built upon the Night Elven skeleton.
Taunka? Nope, Highmountain.
Gilgoblins? Nope, furry Goblins.
San'layn? Nope, Nightborne that suffered a downgrade since Legion.
Just because there were viable alternatives to each race doesn't mean those alternatives would be vastly more popular or that Blizzard is objectively giving the Alliance lesser options. I mean, Broken? Seriously? Broken are not only ugly as sin by design (since they are corrupted abomination) but also short. Both of which tend to make a race unpopular.
