While it is up to the party to set these things...how much more efficient is it to sit around waiting for that "proper" tank over just grabbing one that can get the job done and farming?
There's the big issue; there just aren't a ton of tanks up to this standard. Its great if you can find one, but if you're going to do a run, kick, sit around for 20 minutes, then repeat this all day...are you really being efficient at farming?
And there's having healers who are also up to this standard.
For the record, I do great DPS as a WAR (full 130 STR for almost everything, swapping Defiance when I can, though I'll use my 110 melded set if the heals are weaker or I'm in T13), so I would be one of those these groups are hoping to find. But I'm also more than fine for taking a safer route or grabbing someone who does a little less DPS but can clear without issues for the sake of continuing a farm (as opposed to spending more time in PF than farming).
