paid, if developers add more servers and add, what i said, it would be equal. In public lobby you will have issue with game starting (if everything is independed - why should be it on 1 server) and replay watching. Just create mod with 4-8 people starting (free spaces doesn't matter, untill all people have pairs). Most of people sitting in big queues are not willing to play much. They talk about many things, waiting somebody etc. Also to solve issue you mentioned game has "Quick Aikido" servers. There's 1 server that auto redirects you to server, where you can play pretty soon (max 4 players per room).
