I doubt anybody will demand dps from the party finder. I do not remember anybody demand that in wow once I played it while ago and there was legal dps meter. It have always been gear ilvl that what ppl depend at the begin with it. Or something how you can proof that you have already killed the content. Like in Shiva that diamond dust. In wow it was "link achi". I have not been in any party finder group where dps is the problem(or maybe 1 or 2 times out from 100 times). It is usually something else that fail.
