This is how the (European) female volleyball looks like in general in the last decade or so, Italy NT doesn't even care about using sliders anymore, and they won every game in the last 2 seasons but one. Even this famous 'Conegliano system' is just having an elite setter playing really fast (and all-round great team), because in terms of variance their volleyball is objectively more one dimensional than e.g. Bergamo or Perugia back in the day. Basically if you exclude slide attack (and it's not like this is volume-wise a crucial part of Conegliano offense) - this is just a prime Zaksa/France/Piacenza-like volleyball, nothing more than that.
Also, Conegliano has like the best setter in the world, the best libero, top3 OH pairings at least, and top5 opposite - so if you want to go semantics, it's having superior players what creates this 'system', and not the system itself giving a comparative advantage, because it's not like you can tell Bosio 'do you know this Wolosz girl? tomorrow you'll play like her, please'. In this sense, indeed it's interesting what Conegliano plans to do after Wołosz/De Gennaro era, because besides Van Aalen and Fersino, I can't think of a duo perhaps ready to at least to some extent fill in their shoes.
In the past, male volleyball had athleticism, and female volleyball had variance and technique - now female volleyball is paradoxically more dependent on athleticism considering that best female players impact-wise are much better than the male counterparts, and score 30+ points on weekly basis. Markova's splits comparatively are like anything we see in the male volleyball in terms of 'above average' %s she produces.
And Milano is in the middle of all of this, but without an elite setter, and elite OH duo. What can you do other than create a worse Italy NT? The same with Poland NT: yeah, we had Wołosz, but our OH depth was like a level of back-ups at the top team - and people were like 'where is Wołosz magic?'.
