They already give great tomes through Story Roulette. That's literally the only reason they get run by anyone but new players right now. But unless they bump that reward a good deal, if you're going to force watching cutscenes then your time is better spent elsewhere.

And every MMO is lvl, lvl, lvl... If you don't level you get stuck on the same content.

I reiterate: it was a ridiculous idea to put multiple long cutscenes in the middle of raid. It's absurd really. The cutscenes should have been in solo content between boss trials.
