It might not be such a bad idea
The field of senior Russian women will be over-saturated next season: Tuktamysheva, Radionova, Lipnitskaya, Sotnikova, Medvedeva, Sakhanovich...then you've got the juniors: Proklova, Sotskova, Tsurskaya...and even more potential threats that haven't hit the scene yet: Nugamanova, Gubanova...
I don't know where Anna fits in. With Julia off her game and Adelina out, Anna was the best 3rd option this season. But if both of them come back next season (not to mention the newbie seniors Evgenia and Serafima), I don't think there will be much room left for Anna.
Anna is good enough to be a medal contender anywhere else but she fades into the background in Russia. It think she has a lot more to offer but she needs time to grow and develop. Unfortunately, in Russia's hyper-competitive field, she won't have time to find herself. If she hits a rough patch she'll fall in the standings and her only hope would be to do what Liza T did this year: claw her way up from the bottom of the pile.
Skating for another country might be a good bet for her.
