I get the reasons to have it if someone is underperforming in a tough fight and you gotta know who, but it will also be used in everything if it is official and easily accessible. There will always be someone that is always watching how their party is doing and will tell someone if they feel like it. When it's an officially supported tool that's in game someone will have it in every content, dungeons, trials, it doesn't matter. It will become ok to tell someone they are bad or not up to that persons expectations because SE made it ok. I know people will be jerks and single out others either way but I don't want to give them the tools to do it. I mean if they are doing it now there's at least the argument that they aren't allowed to do that, but again if it's official then they have every right to do it and to an extent, every right to point fingers and single someone out. There are pros there are cons, and I lean towards keeping parsers out
