Well sorry.

But there exists players who don’t want the dungeon/bosses spoiled. I want to be surprised and amazed of what I'm up against and learn through Trial and Error.

One of my examples would be "the Praetorium", my first group which had 2-3 rushers that want to get through quickly so they can farm Tomestones, they kept saying skip CS please and that I could watch the CSes in the Inn.
So I skipped them so they could be happy. But guess what, the scenes are dungeon specific and can NOT! be viewed in the Inn.
So the last dungeon was a bit ruined for me because I had no idea what "Twists" that happened.
So guess what I did, I queued up and again and this time I watched all CSes without skipping, and didn't give the slightest fuck about the rushes. I want my story and that's that.

If it’s too much to ask to experience the game in this way then go join a FC that focuses on End-game stuff and make pre-made teams with people that know what-to-do instead of using duty finder where first timers will be a lot.
