Most comments, and behaviors you see in dungeons, etc heavily leans towards what I said. That, and a side-dash of common sense.
People running roulettes want their rewards as fast as possible. That's why we have multipulling tanks, and AoE heavy play, and why it is GOGOGOGOGO to the point they skip treasure chests.
Common sense, that these same people aren't going to want to dink around with their fingers up in places fingers shouldn't be waiting on cutscenes.
Every single MSQ Roulette I've ever done, people have Sprint on cooldown and they are all in a rush except for the confused newbies who entirely miss the boss battles because nobody mentioned picking up the key. They will round mobs up and SPRINT to the elevators, letting newbies die just to finish it ASAP.
