Can we use ACT to recognize who is griefing the party and report them afterwards?

an officially supported parser won't mean that suddenly it's okay to abuse people over numbers, it has never been and it will never be.

That won't change, but the numbers of people who will abuse because of how open it is will increase. The current official stance acts as a deterrence and people who can use the addon responsibly already are using it for the most part without issue.

If a GM seriously decides to ban me for using ACT I will ... maybe put more hours into studying instead of playing.

I see nothing wrong with that.

Yes such fun wiping on diamond cause the healer things he doesnt need to heal at all lol...

Different contents require different things. Most of the time, it's contents that don't require dps check where people will not care so much. And obviously there is also a matter of priority.

Its even worse on PvP where you can acutally see on the end who did 0 dmg... I had this guy rolling dps but never doing ANY dmg at all... like.... dam leecher...

If they don't do anything at all, that's a different issue.
