I want to preface this by saying that V/m are the reason I started paying attention to figure skating, but I also really like P/C.
First of all, I honestly don't think there is a problem with the coaching situation. We've seen plenty of pics and videos of Scott joking around with Gabby and them all talking and acting like friends and they all seem to have a good vibe with MF. I honestly think she wants both teams to succeed. IIRC, someone was suggesting that she'll give her best choreo to V/M because she wants them to win or something. First of all, while she choreographed both teams' programs, Romain also worked on both P/C programs and David Wilson worked on both V/M programs, so it's not like it's all up to MF. Second of all, P/C put a huge emphasis on the artistic side and they obviously have a lot of say in music and program design and at this point in V/M's career, so do they. So you meet like one program better, but its way more complicated than MF giving one team a better one. They have different music, chose different rhythms, have different performance styles, and which one you prefer is super subjective anyways.
Also I feel like a lot of the discussion around this (not necessarily on this thread, just in general) refers to the fact that at the end, there were issues with the V/M D/W coaching situation. But just because there were issues in that case doesn't actually mean there will be here. It isn't the same two teams, it isn't the same coach. Brian Orser coaching both Hanyu and Javi and that seems to be just fine. And I think people also forget that the coaching situation in Michigan actually worked really well for a long time. As far as we know, it was only the last few months that V/M were unhappy with it. They were the top two teams for a while before anything went wrong.
But even if you think it may not be perfectly equal, there's something people used to bring up fairly often about V/M's coaching with is worth considering. People used to say, what are V/M going to do, leave? Leaving would mean giving D/W Marina's sole attention. Even if you feel your coaches time is more split than you'd like, if you feel you have the best coach (or one of the best), it may not make sense to leave. Now personally, this isn't how I'm thinking, because at the moment I don't believe there's a problem, but I did think this was an interesting point.
