If you want an honest take. I think the biggest reason why damage meters dont exist (besides the obvious drawbacks for toxicity) is because SE doesnt want to spend anymore time policing bad behavior by allowing such a tool create more toxicity. So its not because theyre trying to prevent the inevitable as it already still happens but they dont want to make it any worse.

You guys are really naive to think official parsing will improve the community when in every MMO where its the hard standard, it creates more contempt and problems than solutions.
