I've played a lot of WoW. I had always used DPS meters, and I rarely saw people call each other out. I mean hey, I may have made a comment or two over vent to friends about someone who obviously didn't know how to play their class, but I was never rude to them.

Yeah, there are jerks out there. They're going to be jerks weather or not they have DPS meters. What's so wrong with a meter that tells you how people are performing? What's wrong with wanting to find out who is holding your group back vs a DPS check boss?

Now, I've seen some people making comments about people who are clearly emotionally unstable and bursting into tears upon looking at their meters, without any provocation. That's not the meter's fault. They need psychiatric help.

There are already jerks, trolls, and douche bags galore in this game. Guys. Seriously. Calm down. You might perceive people to be more douchey with meters, but they're just channeling that same douche energy in a different way - namely calling out people who are under-performing.

Imagine how much faster CT runs would have went if you could see which summoners were just spamming ruin II and not casting any DoTs!!!
