DPS meters and parsers are not against the rules.

They are not, themselves, a plague on the community.

Like any other tool, DPS meters can be used for right, or for wrong.

It is a legitimate use of them to point out people who have lower DPS than they should have. It is not a crime. To make martyrs of them is ridiculous-- if they are performing poorly, they NEED TO KNOW in order to improve themselves. Maybe their rotation is bad, maybe they don't even have one. Maybe they're using the wrong skills altogether.

Either way, DPS meters have good uses, and you should strongly consider that if your DPS is lower than everyone else's, with equal gear, the issue is probably on your end, and you should be trying to improve that, not try to start a pity party on the forums to try and say DPS meters are bad and should not be used (which is what it sounds like happened).
