It's hard to reply and not to start just one more battle over the opinion "did Zhenya do well to move" or "is she better now than she wasn't". Like Sasha moved, Aliona moved and the wounds are still fresh and now going back to Zhenya once again? It's the mine field
I will try to reply for myself and my opinion. Starting with Zhenya. Her beginnings with Orser were truly rough and it would make no sense to deny it, that time or now. Then she became world bronze medalist. As for the standings, it was a satisfaction, definitely, not for everyone it was satisfaction in regard of style and skating. There are those who say her skating wasn't as good as she was before and there are those who find her skating more entertaining, artistic etc. It's not a secret that those two camps prefer different things in skating and above all different persons (Eteri/Orser or generally north american style of skating). As for me, my favourite programs of her still remain 2015/16 season FS and 2016/17 season SP. From her new programs I liked Tosca the most, her previous SP I didn't like. I'm indifferent about 2018/19 FS (partially because Tango is not my favourite tune), but I was also more or less indifferent about 2016/17 FS (though in that year's competition it was still one of the best).
But people can argue about those things, focusing on points or artistry, but there is one more thing to consider. Did the transfer fulfilled Zhenya's
own expectations? I can guess she truly liked the new environment but let's face it, one of the main motives was truly to stay competitive in the future and I don't think that particularly this goal was completely fulfilled. Of course we don't have an alternative reality at our disposal where she would stay with Eteri and we could compare how her career would look like in that case.
Now as for Aliona and Sasha. Well, whatever people (incl. me, I would not deny it) objected about Znenya's transfer, Orser was and is still one of the icons of figure skating, some consider him the GOAT among the coaches and were pretty outraged it wasn't him who got the FS award.

So there was some guarantee he is competent to train a star like Zhenya. On the other hand, and I know many will disagree now, Plushy, with Rozanov or without, is nobody as a coach. Sounds harsh but if you try to be objective you should admit this to yourself. It's too much to lose with very little in return. Yes, there was a time when Eteri was nobody as a coach, but at that time anyone who would come to FFKKR and said "let's give her two of our most promising hopes for medals at the highest competitions to train", he would be laughed and ridiculed. Something like that wasn't possible till Eteri built her emprire with her bare hands. Plushy has a name as a skater, contacts and money, but nothing of it makes him a coach. His excessively self-confident claims do not help to improve his reputation.
From the perspective of coaching, it's like taking the latest clerk and make him a CEO. Maybe he will surprise us, but I think one should first prove himself and only then he should be entrusted to take care about the values, not the other way around. As for the girls, yes, if the results will be unsatisfying, I will say that, I don't see a reason why being correct in such case, because it would just prove it was a very bad decision. If the results will be good, that is a question. Many people will be glad that the chance for medals weren't thrown out of the window. I am quite confident that programs could be good, Nastya's case shows Plushy can at least obtain good choreos, but that's not everything. The other thing is working on techique and maybe even more importantly working with the psychics of the skaters. We know that from this perspective Eteri is able to prepare skaters even in the most difficult situations. How many people expected Alina's meltdown before 2019 Worlds, many people didn't expect Kamila will win JGPF just three weeks in trainings after a serious injury and without quads against Alysa or that even Daria would become so consistent throughout the season that she will become world junior silver medalist. In this regard I have much stronger doubts about Plushy's team than with the technique itself.
So, that's my view, I hope I answered fully, I've written that while watching one old, naive but charming western in a way.
