I think it's a very good thing for new players : I remember my first run of those two particular dungeons was horrible, and I didn't get what was happening at all - tried to quickly watch the cutscene, only get locked out/teleported/lost... When I occasionally get there now, I always mark the thing you have to click in order to get the magitek suit keys, activate the cannons... since many, if not most people will just assume you already know everything there is to know... and ignore that some people have fun discovering content/going blind
Another thing that should be made possible, is to prevent people from skipping mobs, as new players often don't know that mobs can actually be skipped, and stay behind getting killed while everybody has already teleported to the next room ! That can be enough to dishearten any aspiring tank or healer...

Yea, yea I know you can re-watch all the cutscenes later in the inn, but it's much better to experience it right during the instance.

And if you're in need of poetics, you can still chain-run the ARF !
