Totally agree. I've seen it multiple times, even on Co-Op. However, I've also seen the opposite. A team that works together well can make up for one player that's lacking, at least to a certain degree. If someone seems to be dragging a bit, hopping over to gank or even just giving a friendly word of advice can help alot.
