From a spectators point of view, less games per match would be nice as it means each game is more important and thus more exciting. This happened in table tennis, they used to play to 21 points but they shortened the games to 11 to make each point more important and exciting. Also bo5 4v4 can lead to a 7+ hour stream which is a long time to sit and watch. Football games and movies are around 2-3 hours long for good reason, any longer is a long time to sit down and pay attention. Just my opinion, the sponsor is the one donating the money so he should call the shots
