Average wait time: Less than 5m.

You would be correct.
What I mentioned would alleviate your initial issues as well. Perhaps not alleviate the lack of players in a specific duty, but that's somewhat outside SE's control.

Okay... do you think I don't understand that the game doesn't have enough players registering for a duty when I get stuck in DF hell? No, I'm in the queue because it's waiting for enough players to register. If it wasn't waiting for players, it would just pop up and I could enter the match, no waiting required. I don't need the game to tell me "yo dude, not enough people are signing up for this, so we gotta wait a bit." to understand why I can't get into a match.

The thing I'm complaining about is that the duty finder gives an estimated wait time, and the estimated wait time is completely inaccurate. My problem is that the game ALWAYS says the average wait time is less than 5m, yet I haven't been able to do a ranked match in the past 2 weeks despite being registered for at least an hour every night.
