There's a reason parsers are considered against ToS now when at the beginning, they weren't. Too many were being removed from parties and excluded from content because they weren't meeting arbitrary numbers players were imposing on others. "You're not pulling 500 DPS minimum, get out." Even if the player was doing mechanics correctly or their gear wasn't quite up to snuff (because back in Coil days, RNG drops were far more of a thing than they are now with Alex's page drops and primals dropping tokens too), so they only did 498 DPS.

The thing is, it still happens- people being removed for poor DPS. They just have to be careful about what they say, if anything, as to why people are removed from a group. My only concern is, if public mentioning of parsing were allowed again, if people don't meet certain numbers, will the rampant removal happen again? If it will, it's best to leave parsers as a 'use at your own risk' tool.
