I can't even think if a group where this has happened.

90+% of the time the tank will ask the other 10 is a split of just doing small pulls middle sized pulls and large. To be your anger stems from one person who did it without asking. This isvery far from the norm if DF.

As for PF, ya this is the norm, most are people trying to upgrade weapons, a mindless grind that eats part of your soul each second you do it, thus to save what little remains they(me included) want sub 7 min rruns.

I think this is just an over reaction to a rare occurrence.
