How would an optional, official parser be toxic?

There is one thing I think needs to be involved in any broad parser, though, and I've been pushing for it since ARR: Relative Potency Parsing. Essentially, you strip away the variance given by primary stats, instances of critical strikes or direct hits (using the chance itself as a rPot-modifier, just as with Det), thus squishing gear variance and removing RNG as to provide a clearer picture of performance.

This is the best solution, so you can easily say how good someone performes on his level of gear, because potency per second doesn't really change with gear, except of SkS and SpS based jobs.
But even this is only a minor inconsistence.
With just potency parsing it is more or less easy to compare the performance, because performance is not DPS including crit luck etc., it's the execution of the rotation.
