If people can't have a satisfactory experience playing the MSQ roulette, guess what happens? People will stop queueing that roulette.Why? SE ultimately doesn't have any reason to care if people can't speedrun this for levelling other jobs. There are lots of other roulettes and methods of doing that. The purpose of this one is to get sprouts through the MSQ. So long as it accomplishes that, there's no reason for them to change anything.
Care to explain how the sprouts will DF those MSQ roulette dungeons once no one bothers doing the roulette anymore?
