DPS display could easily be solved with a system already in game.

[Zaft]

They don't exactly care about parsers by themselves if people don't misuse them, that's why. It's low on the priorities list of actions to take. It is however, a tool the GMs have leverage with to use to fight said players acts of harassment and bad behavior if it involves their use of it.

An old example.

That's the exact image that I was talking about in my post. I've seen literally nothing beyond it of anybody being reprimanded. Ever.

I know this would require liberal use of the paint tool to back up for "lip service"

It still doesn't change that the frequency and prevalence of it would rise sharply, along with abuse of it as a social tool.

What do you describe "abuse" as? Is abuse me telling you that you're doing bad DPS? Is it me removing you because you aren't up to minimum standards for the content? I don't consider either of those as abuse. In fact, the only kind of "abuse" I can think of is somebody being extremely rude and assholeish to somebody else because of their DPS, and I've nearly never seen that happen on ANY game, even ones where nearly everybody uses a parsing tool (such as WoW).
