This needs to be stopped, and immediately.

You misunderstood. 1 person holding up the team (this is debatable as the dungeons can be done without them) is selfish (this as well is a grey area, the new person is watching the CS the SE themselves put into place. They aren't doing anything wrong per se).

vs.

7 other people wanting to hurry up. Damn the noob watching cutscenes, those 7 want their tomes now! That's pretty selfish, even if it's 7 people. They want their tomes, and damning everyone else is being selfish too. Not being considerate of anyone else, in this case the new player, is being selfish.

The new player holding the group back because they're watching CS, could be selfish on the first timer's part, but I think it's more SE's fault for allowing CSes in bad spots.
The 7 others are being selfish because they don't care about anyone else, they just want their tomes. They yell at anyone holding them back from getting their tomes even other people that skip CSes.

Like I said, it's a no-win situation on both sides. SE is being lazy by just saying "Handle it amongst yourselves". Which is good sometimes, but it's obviously splitting the community in half and leaving a very bad taste in some customers' mouths.

Sorry if I didn't explain it well.
