Just had a VA run where on the last boss a BRD pulled and none of the tanks (I was SMN at the time) could pull aggro off the DPS and Echidna just bounced around everywhere. One of the DPS yells at the tanks, calling them a number of slurs as well as being bad. I notice one of the DRKs turns on Grit and maintains aggro for the rest of the fight. Then at the end of the fight one of the healers says that Tank was "bad" for having to use tank stance to build aggro. Now, I'm not sure about gear discrepancies, but I do know the DRK was using the 180 upgraded law weapon, and most of the DPS that I saw had their 200 weapons.

Anyway, got a bit off topic there, does using tank stance to (at the very least) build aggro at the start and then turning it off if you want/need to dps more really mean a tank is "bad?" I just find it kind of backwards that a tank using tank stance is apparently being bad.
