I know the whole idea of duos is doing those between two person´s, but when there is no people to queue and you have no friend´s online is kind of anoying waiting, more if you wanna do feat´s, so what about give us the option to do duos alone? In orden to preseve the nature of duos and avoid players to go alone all the time. Dev´s could put a counter that can trigger when you have waited more then 5 minutes in Queue. If a player get the advice to enter because someone else queue the counter for enter alone will not trigger. A similar idea could be use in alert´s when you have only 3 players in queue and nobody else comes.
