I haven't read the entire thread, and I'm not going to cuz it's really long. But I wanted to briefly put in my own experience with this before cut scenes were unskipable.
I remember having a really bad time in these MSQ ques because the first time I was there I was so engrossed with the story and wanted to watch everything as it was basically a finale for the ARR storyline. I remember coming out of the cutscenes and no one was around. I didn't know where to go. No one was responding via party chat when I asked what was going on and where everyone was. I was literally lost. Though I didn't know what was going on at the time, eventually the party would get to the next progression area and a new cutscene would play for me. I ended up watching all of the cut scenes without even fighting any of the bosses.
Needless to say my immersion was completely destroyed. I was so shocked that I went to the general FFXIV discord at the time (don't know if it was some unofficial or official one) to ask about it. And the respond from them was just "Tough man. Watch the cutscenes in the inn." Which wasn't even really a real response to my particular issue. I SAW all the cutscenes. My issue was that what was supposed to be a finale to the story that I was really into was destroyed by conflicting interests of players just wanting to get through the instance ASAP and not caring about some newbies immersion.
So to be honest, and I absolutely KNOW I'm in the minority here, but I appreciate the changed forced cutscene viewing (with greater rewards), for the sake of those new people who are legit into this really quirky game. That being said, I do agree the best option would be to make those two quests run with NPC's instead of players. But until that time, I think the change is better overall than what it used to be.
