1v1-3 is where it's at though even for private. Why in the world would anyone want to wait in a massive line for nonsense when you can play to improve. It's already been documented in the FGC history that the more time you get in consecutive playing, the more you can find areas to play and improve.
Private lobbies to engage with strong players is never a bad thing ever.
However I get where you are getting at. Lately making an open lobby brings in nothing or hardly anyone joins, sometimes I have no choice but to ask people to play which it is what it is.
