How would an optional, official parser be toxic?

[Fyce]

They already give a table of a few metrics at the end of a PvP session. They could test it on dungeons to see if the community would suddenly turn into a toxic wasteland. Just display the numbers after you exit the dungeon (during the black screen), and that's it. If someone take the time to reach you outside of the dungeon you just cleared to be a jerk, just report, blacklist and voila. But I don't think people would even take the time to look at this table most of the time.
