Some players forget that parsing is already a thing in this game, and making it more widely available would likely help players to a greater degree than it would promote more toxicity than we already have.

Besides, most people parsing with random players are doing so more for their own benefit than to put down anyone else. I farmed T10 as BLM, and the NIN expressed surprise that I didn't play it for my static since I was the only DPS consistently over 500 without Selene, with having to do the LB, and having eaten couple Charges. Turns out that the DRG, by comparison, was barely breaking 400, but at no point was he harassed or asked to leave. He didn't ask for his numbers, and we were clearing fine, so the NIN never mentioned it to the group.
