I'd still rather put up with a tank who has questionable skill than a tank with a d-bag personality or a 40 minute queue time. The challenge brought by a variety of or wow classes and skill levels is what keeps the thing from being automatic and boring.
It still comes back to the fact that d-bag DPS has chased most of the "good" tanks away, and if this makes for new tanks, fine, and at the very least might give d-bag DPS guys who are now playing tanks a taste of what the tanks went through before they stopped queueing up for randoms.
