"But the differece between Ruby and ATLA is that we knew Aang was the special person that could do miraculous feats"

There are no better words to say it. Aang was more than special, he was the Avatar, the one person in the world capable of mastering all the elements. We knew he was powerful and unique (double unique, since all airbenders were killed).

But Ruby, so far, was not that special. Her more special trait was being a prodigy and getting pushed 2 years ahead. There was nothing to even imply she was capable of 1-shotting the closest thing this show had to a Physical God, much less to imply she was part of a long line of OP warriors more powerful than even Maidens.

We knew she was a great Huntress. But nothing implied she could do that. We thought she would simply upgrade her weapon, learn how to use Dust like a mage, improve her Semblance, start using the cool Slayer outfit....but nope, "Part of ancient ultra-rare silver-eyed gods that kill Grimm just by staring at them".
