"With the Pro Subscription, you can invite three friends with Standard level memberships to play with you in any Premium level map" That's really good. It means that four friends could divvy up the cost of the suscription, and one of them could always invite whoever is available to the premium maps. As long as they always want to play toghether, wich is common among friends playing the same game, this seems like it would be quite easy, and even cheaper than the Premium Suscription.
