How would an optional, official parser be toxic?

Snip.

I see, thank you for your reply. A bit off topic now, but does "Duty Complete" from duty finder not work when you are in a Party?

On topic: I'm not against using parser for yourself to help improve your performance, but as many others have pointed out, all the people who wishes to use parsers already use them, so what benefits do we gain by making an official one?
