Hi there,
Back in the day league updates were only done like once or twice during the entire transfer window period. However, now that it is much easier to update leagues, they are being updated more frequent. This is because most users want to play in a league that is up-to-date.
If you log in via the webversion of OSM, you can check all our current leagues with their starting squad go to community and then league overview. This way you can already take a peak which players each team have. If you feel that some teams are unbalanced, then skip that league for a few weeks until it is more balanced.
Considering no one has replied to your post in an entire year, it's pretty safe to assume that you are in the minority here.
