Story falls apart at the end...

[Kerberon]

Go to the inn and watch them. You can still watch it all.

You shouldn't have to watch story cutscenes after the climax has happened. That is horribly un-immersive.

It's like finishing Final Fantasy X without the end cutscenes, then watching them 2 hours after the end credits. It completely ruins the experience.
(If you didn't like FFX, insert any game that had a terrific story instead)

The op sounds like they didn't know that. There is no non-rude option here. Making a new player skip them is rude and it's also equally rude to make 3 people wait because 1 person wants to watch it. Since we have to deal with no non-rude options it's a good idea to make sure people know about the inn option. The mistake is on SE's part cutscenes in group content should never have been more than 20 to 30 secs in length tops.
