Especially since the latest update, me and my friends have been disconnected more times than we can complete a match. Very frustrating, and makes the game feel unplayable at times. We also get kicked from our group when this happens, and often aren't able to get it reestablished without restarting our games.
Suggestions to improve games:
Better matchmaking to make 4 v 2 (+2 AIs) into 3v3s (+AIs). Gear stat balancing between teams. Keeping people of the same faction in the same team where possible.
When the matchmaking sees there are too many players to join, don't bother with telling us that, just re-que again.
While we have the "trying to re-establish connection" screen, allow for longer time. We would rather wait another 10 seconds to continue, than lose the game completely and all our progress.
