the thing about the M+ is, a lot of people try to time it. that’s their goal
when im with friends, we try to time keys too and if we fail we deplete, we do it in 5 man premade tho so we’re all on same page.
but yeah it applies to pugs too, a lot of people are interested in timing/upgrading the key.
check this community, usually a lot of people just do chill runs and chance that someone leaves is minimal.
