Well, since you put it that way, I actually had come across with the similar issue, not long ago. People come to the party, clear, get useless bonus because reasons, grab loot, leave. Frustrating all around.

All of the grr.

Yeah, I'm in full agreement here. If you and the party intend to spend time to farm, your mind is focused on farming.

If you new players need a clear, grab some FC members or your friends. Don't ruin our flow with your looting and scooting.
