Honestly? If I see a duo with the same tags, or... like [HER] and [HIS], I just look for the next game. Considerable experience and hours spent in this game have already shown me that playing with such duos is significantly worse than having every player in a three-person team solo Q.
In these games, I'm only needed to replenish the squad and get the game started.
90% of the time, these duos never want to cooperate and always play alone, often constantly drifting away from you without any communication or ping.
