Realistically: what is the point, every point you made can be used against your argument. I do it when I can because I find it fun, but I can see why people skip it: No reward, the fact that a team of mediocre players get nothing from this challenge at the expense of multiple wipes because a numb nuts kills himself and the group needs every gun they can muster. So why would they even attempt it when somebody can get a Crota checkpoint and they can fail miserably for a legitimate reward.
