All I can say is this: you guys have run in some weird-*** groups. I've yet to have to deal with craziness to that extent in FP runs. Gen chat is another story entirely =p
Ha! Can't argue with that.
A while back, I had a lot of free time but little to do with it, so I ran a LOT of 50 HM FPs through GF. I would say that probably 5%, if that, involved bizarre/cruel/rude comments... and most of those were from people who were bored out of their skull from having done the runs so many times. And probably not even 1% of those people were intolerable. Most of the time, my GF runs are pretty quiet. I've ignored waaaaay more people over not playing their queued role or being a jerk over a mistake than I have ignored people making strange comments about NPCs.
