They had no other way of knowing that that specific DPS was not performing optimally, it could've been another dps, but they pointed out that specific player. The enmity list isn't a good judge either as it's not a viable measure of someone's DPS due to abilities like quelling strikes. Adding an official parser would cause situations like these to become more common. While I am not against their use to improve performance, it is a tool that is too likely to be abused and already is in the current way players have it. When suggesting something, something that should always be thought about is "How will players abuse this?"
