"You suck, you're only doing XX dps" is not friendly advice.
Friendly advice wouldn't even need to include actual dps numbers either. Just point out their rotation seems to be bad and point them to where they can read about improving it.
That's the thing, though. Even friendly advice with parsed numbers is a bannable offense. There's no amount of friendliness I can imbue my statements with that will change SE's stance that using parsers will get you banned. The most I can do is be so polite that I convince my fellow players to conspire against SE and allow me to break the rules with no punishment.

For the comment that time-to-kill tells you if DPS is low, that only tells you the dps of the combined group. It won't tell you the why of the matter, only that something's up.

As to the assertion that numbers are unnecessary, I have to disagree. Say someone tells me "Hey, your DPS is a little low." This actually provides me very little information. Is my DPS barely below norms? Is it well below norms, but they're beating around the bush so I don't report them for harassment? How low is a little low? How low is well below? Now, if they say "Hey, someone with your gear should be able to squeeze out about 100 more DPS than you are," I suddenly have a much better scope of how I compare to the max. I now know that I'm probably about 75 DPS shy of the norm, and I can try to identify why. That's not possible with vague assessments, especially if it's coming from a time-to-kill measurement instead of actual numbers.
