I cannot begin to fathom the thought process behind putting a duty finder group at the back of the instance queue when a random member fails to accept the queue. It is unbelievable.
Players A, B, C and D (from different servers, who don't know each other) join the queue, get formed into an instance group and wait 10 minutes for an instance to become free.
Player D goes afk, falls asleep.
Players A, B and C are now sitting in a queue that is GUARANTEED to fail when it pops, because player D will not accept the group. When this occurs, a new player (usually DPS, since they have the longest queue), gets placed randomly in the queue, and the timer resets for taking an instance.
Repeat the process; if one of the players now goes afk (which is more likely given that the three remaining players have now been waiting 10 minutes for a failed queue), that player gets replaced and the process repeats.
I don't know about others, but eventually it gets to a point where I just throw my hands in the air, say "screw this" and go and do something else. I may or may not remember to click the withdraw button through my exacerbation, which may or may not guarantee the remaining members a requeue when the next queue pops.
This is... unbelievable. It defies logic.
How it should work, and how it works in every other iteration of a duty finder in every other mmo:
Players A, B, C and D queue for a dungeon.
Player D falls asleep.
The queue pops, players A, B and C click accept, and player D does not.
The queue fails. The dungeon finder takes the next-in-priority DPS from whatever group they are in, places them in the group, and re-pops the instance. Players A, B and C get their "average" queue time pop, plus a little bit extra for the failed player D, instead of potentially 4 to 5 times the "average" queue timer depending on their luck.
End result: The average queue time potentially gets _SLIGHTLY_ higher, but becomes an ACTUAL representation of the average queue time, rather than a time that sits somewhere between "yay everyone accepted first time" groups and "omg I've been in the queue for an hour and a half and 5 people have failed to accept" queues. Furthermore, the queue is actually a QUEUE, meaning that the person who queued first gets in first.
