Not everyone stands around waiting for people to call out hunts. I have had many times when I'm. Scouting and come across a group kill a A rank, so I join in and let my party know, how is that selfish? Or when I find a mark that no one has I let my party know let them get in the zone and then my Ls. I never lost credit the only time I did was when I attacked one and it's had lighting spikes and it killed me but that's my fault. Other then that I've never got anything but full credit on a mob I found.
