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

Parsers are also against the ToS, but that doesn't stop players from using them (not that I'd argue players shouldn't use parsers but the ToS doesn't stop actions from happening). Which is why you don't see an abundance of misuse with them..

They are widely used for all and any content because people want to see their DPS. The fact that they are against ToS has nothing to do with the fact that there's rarely any misuse of them.

Isn't it interseting that you seem to imply that the viewpoint of everyone else is invalid... hmmm.
Since adding an in game parser actually affects these very people, not just you?

Having lack of perspective certainly doesn't make someone's opinion invalid. That being said, parsers already exist ingame on a wide scale, where are all the toxic effects that these player(s) are mentioning?

Please don't resort to constantly mocking progress in a single game.

It's funny how me pointing out a fact in this case, your current progress as it stands, is somehow mocking your progress. You're welcome to bring your viewpoint into the conversation but if it comes from someone that has little to no experience raiding, using a parser or meeting any DPS checks when content is relevant then it should be pointed out in the context of the conversation.
