You really need to do it with friends or people in the FC who will do that for you. To do this you are asking a lot especially for people who have done it a zillion times before to wait through all of the cutscenes. The reason it is speed run in roulette is because of this basically they have done it so many times that they just want to get it over with. It's not exactly new player friendly but it's their time also so if nobody else in the group wants to waste the time nothing you can do about that. There simply isn't enough new players coming through at the same time anymore to build full on story runs. There used to be tons when the game was starting out and people would group to do this but now it's such old content that nobody cares about it.

This isn't the climax of the story by any means even post level 50 the story is still ongoing and will continue into the expansion and new level cap.
