Singular, actually. He acts rather predictably when cross, if you've been observing.
I stand corrected, thanks for that. Although I will say, however, that the term 'Amaurotain' does get used instead...

...in the French version of the script.

Humor aside, I've always found it strange that anyone would view a character's claims of being 'superior' unironically. Generally it points to a touch of narcissism and a dollop of hubris. So whenever you see an Amaurotine or Ascian sneering down at other 'inferior' races, I wouldn't have expected anyone to seriously buy into that at face value and kowtow to them because of it.
It's actually interesting how much contrast the Amaurotines have with FFVII's Cetra, who are referred to by others as 'Ancients', who are referred to (by others, not themselves) as caretakers of the planet, and yet you actually get the sense that they genuinely lived in harmony with the planet rather than it being something that they claimed ownership of (and the nature vs. industrialism theme of that story probably helps their portrayal as well). A little bit of humility goes a long way.
I don't mind learning about other 'Ancient' societies, personally, especially if they're completely unaffiliated with the ones we've been dealing with in the past five expansions. I think that there's a good opportunity, as we travel to other continents, to write about other such societies that bring the Amautorines and their narrow viewpoints of the world into sharp contrast. The world's a bigger place than we know.
For good or for ill, however, I think that we've seen that pretty much any mention of the Amaurotines to date have been consistently (and unnecessarily) controversial. And rather than offering up more opportunities to be heckled over, it probably makes sense for the writers to finish up the existing plotlines and quietly write them out of the story. Sensible thing to do in response, really.
