How would an optional, official parser be toxic?

How would an optional, official parser be toxic?

So long as it's private and for just your character it wouldn't be, in fact it would probably serve to improve the general populations play quite significantly. As a tank or healer it's very obvious how well you're doing at your primary function, as a damage dealer... not so much.

Edit: although maybe Shurrikhan has a point about personal parsers and hiding the results from the rest of the party. /thinking.
