The 4v4 No Share Matchmaker used to have a problem with incompatible client versions resulting in failed matches. That issue has basically been resolved, so the 4v4 No Share Matchmaker now works as well as the 4v4 Full Share Matchmaker does. So, if you want to use the matchmaker for 4v4 Share Until Death matches, feel free to queue for 4v4 No Share (btw, you can join multiple queues simultaneously if desired). The 4v4 No Share queue features a lot of popular team game maps, such as hilly, canis, wonder, open palms, tabula rasa, potem, mapgen, etc.
