How does SE justify these ten min enrages, but doesnt let anyone know their dps

[Reynhart]

Let's take a RDM for example. Fleche should be roughly 9.5% or more of your overall damage (based on a few random high-end parses), but looking at logs, you notice yours is sitting at 6-7% with 4 less total casts. DPS gains right there.

So, again, you need a parser to realize some of your CD stay unused ?
