DPS is the job of DPS.

[Reynhart]

Of all of them, "easy" isn't.

Then chose between "fast" and "smooth"

The real problem lies with people who straight out refuse to optimize.

The problem also lies with people who don't have the patience to teach other. If your new healer/tank tries to manage a mass pull and the group wipes once or twice, most people will just bail out.

Now, admittedly, reporting aside, they are technically free to do that; we can't systematically defend against such except by punishment after the fact. But in any reasonable situation not already reportable, does "majority rule" as a basic description fall apart?

The problem with the majority is that not all roles bear the same responsibility, so they don't express their opinion based on the same premise.
