I think I understand the some people's situation though. Well, you see when you hit queue up for the dungeon, and the system throw you the more than 30 minutes wait time. Who would have thought that the duty will randomly pop at 5-10 minutes mark though? To me, well, I was still around reading while waiting so I can still click commence when the queue arrive early, but for some people they might be away preparing food or might be in the toilet or something~
