DPS is the job of DPS.

[Shurrikhan]

Can we just agree that majority rule is not a reasonable standard to expect people to follow?

You example here, though, depends on a behavior beneath a minimum of what any reasonable person would require to consider the majority therein not cheating and/or griefing, each reportable offenses. Moreover it relies on double-standards, whereby that majority rule is not legislating for itself, but rather creating two bodies, and then legislating over that second body in which it has no actual participation.

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?

Majority rule will always suffer from misinterpretation, unfair judgment, and deposited responsibility, as per your second example — which you'd offered a perfect personal counter for — and I, myself, will likely find situations where I'm likely to stretch how I interpret the opinions of the remaining group members, such as when the tank in a "let's go slow" party who knows he can survive on Regen alone, but as our only true arbitrator is Vote Kick, I don't see how majority rule isn't an apt basic description.

Though, admittedly "striking a balance between or as to circumvent effective conflicts" may be a better definition, albeit a mouthful.
