It's kind of a Catch-22. Let's be honest for a moment, an in-game parser that could be seen by all party members would be used to attack other players. That's a fact. Does not matter if this a toxic or non-toxic or whatever community, it's just the way of the world. We all run the instances. Constructive criticism is NOT the norm. Just being real.

That being said... I'm still all for it. The good outweighs the bad in my opinion. It's a MMO. Get thick skin or get out. Use the criticism to fuel your improvement. It works this way in all competition. Be it sports, work, school, etc.
