Happened to a guy I was playing with yesterday, the fire team leader was letting some guy make up for his lack of power but ended up kicking him right as we were about to beat the boss in the 1280 nightfall. Happened again to me just now, the fire team leader didn't like how I was sniping from up top so he waited until the boss had one hit left and kicked me from the 1280 nightfall. I'm not saying don't completely remove the option to kick people but, instead once the boss gets to like a third of their health left prevent people from being kicked. In order to prevent people from wasting their time. Because there goes the 1 hour I spent carrying people through the nightfall that I'll never get back.
