Why don't they just auto unlock those cutscenes from the previous Coil, for everyone after the next one comes out? Then those who weren't fortunate enough to defeat those turns can go watch them. I personally believe it's a load of bull that people want to only do Coil for the, "story". They want what other people have, but don't want to put forth the same effort.

They want it for story - then give them the cutscene for free
They want it for loot and story - do the normal version
It's too hard - when subs start suffering terribly, SE will nerf it
