How would an optional, official parser be toxic?

The issue with this is that it doesn’t give you anything to go on—it’s literally just a number with not a lot of context behind it.

Unless there were players sharing their numbers, general baselines could never be established when it came to performance. A BRD seeing that they are doing 12,000 DPS (random number) doesn’t tell them anything. Is that good for their item level? Is it bad? Could they use improvement, or are they doing well enough? You don’t know without other numbers to compare it to. They could think they’re doing well when the average could be 15,000 DPS (again, random number).

Easily solved with a rank attached to the number like a star system or a statistic like average dps for that content or something similar. It doesn't even necessarily need to be based on actual performance of other players and could just be threshold numbers that are set by SE. It doesn't even need to be ranked across the entire scale of players or have much granularity to it. E.g. a 3-star rank in a 1 to 3 star rating system might be achievable with what would be roughly a 75th percentile on fflogs.

It's not perfect to just see your number and relative rank, but it's at least informational. A full parse will always be better since it contains so much more information, but I would definitely approve of some sort of performance information being given out in-game.
