actually you're making your job harder. healer not healing and dpsing? let them pull agro watch them die, dps over agroing? let them die, players on a general basis being stupid? let them die. instead of trying so hard to do your job watch as they attempt to live or coordinate without you. if people cannot simply lower their damage or hit your target or even heal you going out of your way to let them continue that only shows its ok for them to do that. so next time they do that just let them die
