I think it would be easier to wait if we could do something while we wait, like a solo match or some practice zone. Right now the only thing to do is to spam on the discord chat lol.
What TehMud said it is true. I have made queues for only 2 maps before because I was looking for 2 blueprints that I was missing and the queue was much longer. IMO too much, maybe it was coincidence that they were longer. Although If that is true, IMO that needs a review, I am not an expert on queues, but if most ppl picked all maps then I shouldn't be that much longer, even if I only choose one or two maps. BTW, a friend of mine and me queued for the same maps and we got together 2 of 3 matchs, so that make me think that the missions you select are considered in the matchmaking too. Maybe it was simple luck, I know that the data its not that big to jump to conclusions.
At release I don't think everyone will queue on all maps, as they will have to unlock the new maps and then you will go hunting rewards or maybe you won't like some maps.
Even if the queues are much better than some weeks ago (they really improved a lot) I think that they need some stress test. If the queues keep being of 5-10 mins, and I know they can be longer by experience, I think a lot of ppl will leave the game before trying, so better to fix that before the release.
