If they found a way to magically fix the Wolves Den queues, I don't think people would mind the quick matches or the learning curve. Yes, getting focused 9 matches out of 10 as the healer is frustrating, but if you could play 10 matches in an hour you could start to learn some counter strategies.

Also, they need to improve the in-game communication about PvP abilities. I suspect there may be people who tried out Den early on when the PvP specific abilities themselves had to be unlocked who may not have ever realized that you now have all the actions by default. Heck, there may be people who started after that who don't really understand about the PvP actions - the active help only even mentions their existence in the rewards category, not the Den help entry itself. Maybe even going as far as adding a small quest to unlock them; something like after unlocking the Wolves Den in Duty Finder, a new quest asks to you talk to another NPC at the pier who then grants you all the abilities.
