At this point, the Main Scenario Duty Roulette is full of people trying to get an easy 300 Phil tomes (and trust me, first timers, you'll be there too soon enough). These people can't form their own group because the only way to receive the bonus is to queue up solo. If you want one of these in order to enjoy the story, why would you use the DF anyway? With the Party Finder, you could easily create a "Let's enjoy the story!" group and then shout in Mor/Northern Thanalan and get a group with like minded people.

I'm not saying I'm one of those people that rush others. Heck, I'm the tank that sits at the entrance waiting for everyone to enter, but, there are simply too many people that rage or rush in to reliably enter CM or Prae through DF and expect people to wait while you watch all of the cutscenes (depending on your reading speed, Prae can take an extra 20+ minutes if you watch all of the cutscenes).
