I honestly stopped doing MSQ Roulette ages ago when I stopped needing Poetics. Unless you absolutely want to help people get through those instances there was never a good reason to run that Roulette over doing anything else, like PotD for example, after getting all your Roulette Daily Bonuses for the day. That said, this ultimately should not impact anything in a negative way. If anything, it'll make people who used the Roulette solely for the sake of farming EXP and Poetics realize there are better ways by making them stop queueing for it, and those that actually want to watch cutscenes are no longer forced to skip them as people that have already done those instances and continue to queue for them accept the cutscene viewing.

In the end, everyone will get something out of this.
