How exactly do you know it's a design choice and not a bug? There's lots of bugs in games where coders implemented something it works in the sense that it functions and doesn't crash. But the devils in the details and it's possible no one noticed this anomaly.

I'm still leveling I've only seen the reserving instance after I got a full group once. I've seen people fail to click the button when a group forms and I'm definately not being placed in the back of the queue. I don't see how that's possible when my Sastasha queue pops for the first time after a 40 minute wait then pops 3 times in 3 mins due to members not clicking their button. Hard to believe that would be an example of me being placed in the back of the queue.

It sounds like the queue system has two behaviors with the one your stuck in only happening in dungeons where there is a wait list to get an available instance. At least that's how I understand it from this thread. Same system with 2 behaviors depending on various conditions sounds like a bug to me.
