How would an optional, official parser be toxic?

[SleepyNeko]

What if your school/college transcripts were public record?

Its a nice analogy except it needs the caveat of the transcripts being taken from random surprise quiz that you did not know contributed to your final grade, or suddenly you are doing exams that were meant for students one year above you (iLvl difference)

As for the topic, I don't think having an official parser will be toxic in itself, but it will provide toxic players with an excuse to "officially" use it against others. Be it calling people out in a toxic manner or silently excluding players due to more availability to record logs and post them on fflogs.
