But sometimes, it is definitely the case. 3 times now, I've gone into a Big Team Battle game on H3 where a team of 7 people quit because we were losing. Determined not to just give the other team a win by default, I would play hide-and-go-seek with them. <_<
I lost all 3 games by at least 15 (my teams all quit when we were down by 15-25). One of them thought that the other team was hacking, one complained about splatters (they must not know how to jump), and the other one betrayed me at least 10 times, and then they all quit.
