I used to be one of the people who just asked others to skip the cutscenes if the majority of the group was not running these dungeons for the first time, but this was when it was one of the few, and best ways to farm tomes.

I do think that SE implemented incentive incorrectly. If they were trying to encourage us to help newbies through the dungeon, they should have made it so that the cutscenes were unskippable for newbies, and the fights were only able to be initiated after all party members were out of the cutscene. Instead they gave large incentives to join the duties, and the ability to burn through that content fast so that it gave the best payout.

The way that I see it now is that there are so many options for tomes, it really is on the veteran players to try to cater to the new players at this point. If you're queuing up for main scenario roulette you should know what you're in for, and budget your time accordingly. It is separated from our dungeon roulettes for that very reason.
