Why are low standards for dps acceptable?

[DPZ2]

Comparing yourself to the bottom of the barrel does absolutely nothing, and this is another example of why measuring your DPS by your enmity is largely inaccurate. Enmity-reducing abilities aside, you can be second highest enmity at 700 dps because everyone else is still pulling 500. That still makes you bad.

Oooooh. Finally, a solid number!

500 DPS is bad, people. So all of you out there are expected to pull at least ... um, 700 is also bad? What is 'good' then? And in what context?

Inquiring minds think this is also a 'spurious statistic', but are willing to be proven wrong.
