I think by pushing an admittedly nervous dancer as hard and prominently as he has Skorik, without giving her a chance to grow into the rep and to feel confident at each stage, but, instead, asking her to carry the company, Fateev has not only done as disservice to her, but also to the other dancers whom he could have grown concurrently by giving them similar opportunities.
Exactly, and as a result more pressure is given to Skorik because one gets the impression that she is being promoted at the expense of everyone else in the company, therefore she's not allowed not to be extremely amazing.
Regarding Esina, another problem is the roles she's dancing. Le Corsaire does not seem to be a role she's famous for, nor is it a frequent ballet in Western Europe. One would say she is bring western style back to MT if she's allowed to dance all the great modern choreographies she's excellent in, or Swan Lake and some others. Her recent performance as Medora, which is also the closing performance of the season, received many controversial comments, and personally I would rank it average, but again, why isn't she given the roles she's good at? That also does not seem a role Manuel Legris is specialized and could teach her. And when Manuel Legris came there, she was already principal for quite a while.
I don't think "chances are great" other talented ballerinas could find similar opportunities. Esina was offered directly Principal status in Vienna when that company was emerging. Any other MT talented ballerina would take such a chance if there is any. But how many ballet companies are there altogether? How many of them are in need of principals? How many of them are willing to take corps-de-ballet directly as principals? And how many MT ballerinas are allowed roles like O/O in their first two seasons now? I think Esina is facing similar pressure as Skorik is facing, many people both in and out of the theater would not excuse them not being extremely exceptional. It's not that the ballerinas are guilty for this, but they are the ones to be easily blamed, because they are "not accomplishing their duty" as expected.
Personally I loved both Skorik and Esina as young dancers, but not so much now since Skorik "has to make" so many mistakes before giving a good performance, and Esina is appearing not in a role best suited role for her (I even liked her very much in her recent O/O guest performance, but not so after her Medora). I am willing to accept them, but just cannot when seeing them not so good, taking into consideration that others might be better if allowed to perform.
