Yeah, glad to know that sitting and waiting around for the DF pop is the highly prized playstyle encouraged here, rather than making efficient use of time by completing other tasks while you wait. Unless something has changed, I thought that you also had to wait on the cooldown of switching to your chosen class before the queue actually locked you in....

That would mean 15 seconds to finish ANYTHING you were doing, from combat to crafting/gathering to have enough time for the 30 second cooldown. I could be wrong, though...
