>>117986800It's 10,000 hours to become a master. That's a full five year commitment and Ty Lee became a master acrobat in addition to learning the apparently secret technique of chi blocking. So: no. It's not realistic two girls who were court pages in their youth spent that time by 16. To say it's reasonable because "medieval peoples" ignores that both Ty Lee and Mai were children of privilege and would not only have other formal education, but also had opportunity and resources to give over to leisure. You'll notice one was an airhead with family problems who joined a circus, and the other is a depressive child of a career bureaucrat in her introduction literally bemoans having nothing to do. Don't seem to be hyper-motivated individuals.
>But a Katara goes from barely knowing waterbending to mastering in it with just a couple months of official training. >But Aang masters airbending and Toph masters earthbending by 12>Aang even pretty much masters waterbending and earthbending in under a year. Yes that makes learning skills fast consistent in the series' fantastical setting not "realistic".
