Same thing that probably happened to us being able to have roles when flying the airship and actually flying it around as a group (From Secrets of Eorzea interview) >.>

But yea, I wish this system was in the game. Probably would have kept a lot of people subbed and kept raid groups going. Now it is really hard to find people to do stuff with. T_T Being able to practice where you are stuck would be super helpful ^^
