It makes sense from a plot view. You are playing the game specifically from the perspective of Noctis, not his pals. In Metal Gear Solid 2 we dont ever see what Snake is doing because we're Raiden.
Hynad does put out a happy medium though.
Yet we have a few cut-scenes that are not from the perspective of Noctis. With Luna, Ardyn, the emperor and Ravus, for example.
So that point doesn't really stand.
