Although I'd love this as well, the only problem I potentially see with it are high ranked players getting constantly queued against low ranked and inexperienced players, and completely demolishing them over and over. The priority is given to low ranked players to go against low ranked players for fair fights first, and then when there are none, high ranked players are finally allowed to join. I honestly do hate the wait time as well though, and I think this problem would be fixed by simply adding more incentive (such as rankings, rating, and rewards) for people to queue Wolves' Den. Inexperienced players would go against similar people, and highly experienced players would go against others because there is a reason to queue again and everyone is happy. No competition = no participation.
