A very simple mistake that was hilarious the first five times and just sad after that. It shows people just do not learn from their mistakes:
We were running crucible control against six others. As we stood inside of the building, a titan in Chatterwhite runs up a ramp toward the open hole in the wall and in mid air I shoot him with my shotgun. He does it again and again and again to the point I started yelling "PULL!" like I was shooting skeet. The entire team was rolling on the floor laughing.
Eventually after eight back to back kills, he started coming around the back...where I met him three more times before he rage quit. Max agility but really low armor. I stuck him with a low hit shotgun too which made him feel even worse.
