Continuous GW Play and sign up reduction

There are games that allow you to play levels as soon as enough players have joined. Marvel has a few. Basically, waiting for players to join battle. A few minutes tops. As soon as player slots are filled the battle immediately begins. Which also means reducing the number of required players to sign up will increase playability. I would say 3 to 5 with the option of choosing which team to wait for. Teams with higher numbers give greater rewards which will make people want to wait for 5 man teams, however allow low peak times of play with smaller 3 man teams, when people aren't playing or are sleep based on world time zones.
