Probably the most screwed up AFK players I experienced occured during last week's nightfall. Got invited to join a two-man fireteam and learned their strategy was for us to stay behind the column under the drop-off, they take turns firing potshots at the boss with their solar launchers , while I switch to sunsinger and hide in the corner -_-. Don't know about anyone else but that has to be the most boring and unsatisfying way of completing a nightfall.
