We did add DKs to make it easier to find tanks, and it has. We also added Dungeon Finder to make it easier to assemble groups, and it has wow gold. Neither of those designs guaranteed you could find a tank within 30 sec, and really nobody expected them to.

At the end of the day, tanking is a lot of work. Tanks are generally called upon to lead groups, set the pace of run, and keep things organized. Even a healer by contrast can kind of go along for the ride, healing here and there without really understanding the encounter mechanics. (I'm talking the 5-player Dungeon Finder experience here.) If there's a wipe, it's often blamed on the tank. If the dps pull aggro wow gold, it's often blamed on the tank. It takes a certain kind of player to want to tank, and really we're not trying to change that. We just want to do what we can to keep you from having to sit around too long waiting for a tank, up to and including you deciding to tank the run yourself.
