I disagree with anyone who says meters will not make a notable difference in DPS. In my experience anytime you keep score publicly on ANYTHING. People perform better, most of us have some pride. I think the strenuous objection you see to them tells much of the story. As a healer I can tell with absolute certainty that there are people who are doing practically nothing. Those people deserve to their performance to be shown for everyone to see. It is beyond incompetence it is, you will carry me.

In a 4/8 man run on your way to the 1st boss if the tank can't hold aggro on trash or the boss, can't move mobs where he is supposed to, he gets called out or replaced. If healer lets people repeatedly die...same deal. You are all OK with that. If a DPS or two is performing apathetically it becomes a large burden on others and can cause wipes. Right now we have to guess to figure out who the problem is. It isn't fair and it isn't right. Apathetically bad players can comfortably hide right now as DPS. I am of the opinion just publically making meters available will fix a large part of this and I say the loud opposition to the possible inclusion of meters is evidence. If people didn't care about others knowing how bad they are, If there was zero opposition, you could make the argument they would have no impact....The size and magnitude of the voice against convinces me of their impact, they don't want be outed, they don't want to lose their free ride.
