Everyone readies up for 2v2 or 2v2v2 and..... One person leaves, the game starts, and someone doesn't have a teammate. Can it automatically unready players or at least have a countdown to avoid this?
I agree, this seems to be a pretty common problem. I think the best solution would be the ability to unready, and a countdown after all players are ready to give people a chance to unready.
This and many other features to the lobby, friends, and clan systems have been talked about in other threads. It is an issue, but because it doesn't revolve around the core game mechanics and gameplay it will be updated later on in beta. It is however on the to-do-list. Just not a high priority until bigger features have been added.
