I want to understand what happened in the 2012-2013 season with the ladies' figure skating field. Why was it so easy for Yuna Kim to dominate it after her return? What happened with her rivals?
Kim skated in only one major competition in 2012-2013 season, and that was Worlds.
To understand what went on, check the scores

After the SP, only Kostner and Murakami were within sight of Kim's score, so in the Lp, let's see how they did. And Caro had a fall in the SP.

The tech panel was pretty hard on underrotations and edge calls, so most girls doing triple triple combos got UR on the second jump in the combo. Even Kim got an edge call in the SP on her 3flip. Worse, most girls were doing 3t/3t's in the sp, and getting called on a ur, which put them at a techical disadvantage right there to Kim. And those doing both a 3flip and a 3 lutz were getting an edge call on one or the other.
Lipnitskaia was not yet old enough to compete. Mao.had a dreadful SP. She singled her 3loop, and ur'd her 2loop, the second jump.of her
Sotnikova and Tuktamyshev did not score well in the SP. Adelina was, as at Sochi, only doing 3t3t, but got called for ur on the second jump. This put her at a disadvantage to Kim.who had a clean 3Lz3T
In the LP, Murakami did not skate well. So the only remaining question is, what happened to Kostner in the LP?
Check the protocol.
Kostner's base value was only about 50. Kim's was 58.22.
No way was Caro beating Yu Na at that large a tech disadvantage.
