Actually, I agree with this decision of rotating the squad frequently because by doing so a lot of players who do not generally have enough play time or any play time at all will be able to get a decent amount of playtime. We generally see that the squad is not rotated very frequently unless there is an injury problem or the players in the main 11 are not 100% fit for the next match. But now there will be a better rotation of squad and that is going to be e making the competition a lot more interesting.
And this is especially felt in the national teams.
Many players show a lot of potential in the younger layers (under-16, under-20, under-21), but then they have few opportunities in the main national teams. This is not because they are not good, but because they have little opportunity to play, since the most experienced and with the best qualifications always have the upper hand.
Of course this is normal. But if there are more competitions, these players will have more opportunities and that turns out to be good for everyone: players and clubs.
Nations league meant to be a competition that allow more talent to have more time to show off , but in fact ... they are all take it too serious making there is still not much space to grow for young players to show off , they keep putting their best 11 selections on the field rather than having a joy to give more young players a time to play.
Senior players even a bit frustrated with this new competition due the busy schedule in the club so yeah better not to take this nations league too serious and give more time to young players tbh.
