Why are you doing farm parties in pf with randoms though? If you can't get 8 people together to do it, you need to spend less time griping about carries and more time making friends. The raiders in this game are odd that way; no one expects to speedkill stuff over and over in the hardest content in the game with randoms. Yet in this game they complain when it happens. In most other games, if you want to do this you do it with a guild specifically designed for endgame raiding.
