Her skating is more complete and full than Tuktamysheva, Trusova, and Shcherbakova. In Alena's current condition Valieva is ahead of her too. Ironically the other two new seniors - Usacheva and Khromykh - are the ones matching Valieva with the combination of speed, skating skills, elegance, and power that people refer to as "senior skating." Tuktamysheva and Shcherbakova have their own unique style and voice on the ice which is another part of "senior skating" but Kamila has her signature and iconic moments on ice too with her flexibility and leg strength just like the great skaters in history.
Sinitsyna should be in bold too. Wow it's amazing to see the Russian ladies dominate. If Samodelkina gets it together and makes the junior worlds team they could have possibly 12 skaters above 210 points aka 12 skaters who would have won World Silver 2018. Amazing.
I will shred you. The fans who wanted/believed in a 3A Olympic podium were blind to the future just like the fans who thought that Medvedeva and Zagitova would have any shot of sticking around once the 3A arrived. For Valieva-Usacheva-Khromykh the same is true. They only have a couple years themselves before Akatieva, Zhilina, and company. That's the way the system works right now. But if you don't like Kamila don't worry, she will be no exception, she will struggle with motivation and growth just like Zagitova did after winning when facing off against a girl hungry for titles like Akatieva. Only someone like Tuktamysheva who has the luxury of being the top dog at her training camp can stick around.
Why should Kamila not expect to win Rusnats last year? She's an athlete, she has an athlete's mindset.
Why should she not be chosen? This is not special. Tuktamysheva was "chosen" in 14-15. Medvedeva in 15-16 and 16-17. Zagitova in 17-18 and 18-19. Kihira threatened in 2018 through pure BV advantage but she took herself out of contention with inconsistency. Kostornaia seized the opportunity in 19-20 when Trusova showed nerves. Anna was clearly the chosen one in 20-21, scoring better at Rusnats 2021 with 2 quads then at Rusnats 2020 with 3 quads.
Valieva continues the cycle. In fact I'd say she's more deserving of being "chosen" because she has it all: like you said Anna has spins and Sasha has quads and Aliona had components and they were ALL rewarded as new seniors for them.
here is the narrative I just described in chart form. Notice the PCS boost they all get in their chosen season including Kihira in 18-19.
