I support this. After reading through this thread I will say this.

Why are people mad over this idea?
No loot, no achievements, no progression PERIOD.
Just cutscenes.

This isn't even a casual vs hardcore content thing. Us casuals are NOT trying to get a free ride. We just want story.

But I do agree. SE would have to spend time retuning the content.

I say this:
Offer a quest that awards all the cutscenes.
We talk to some NPCs, and get a "Echo Crystal".
It lets us watch All the cutscenes from the innroom.

Boom. Problem solved. No Raid is even touched.
No loot, no exp, no echo buff, nothing.

Everyone is happy.
