The worst is the people who just run out and die. Maybe the kill a dreg or two and then just run straight at that captain. Or they make sure they're directly next to omnigul where there is no easy way to rez. If you do rez them...30 seconds later *guardian down* - rinse and repeat. This week everytime I tried to do the weekly heroics at least one person was either AFK or playing bullet sponge. It's not a problem, it's a plague.
