May I point out that among all of the other amazing things Korra has accomplished as an Avatar, she is still able to go into the Avatar State (and actually fight against going into it when needed).

All of her past Avatars are gone, so the Avatar State is empty except for her and Raava. She was alone and had to rely on herself.

That means that all of Korra’s bending abilities were her own. That wasn’t the experience of the past Avatars helping her out. She is truly an amazing bender on her own.

She is a legend and an inspiration, and a strong and courageous role model for women and men alike :)
