...could it be more consistent in which cutscenes can be watched? And could it include non-cutscene conversations too? There has been at least two cases where I've been forced to watch a cutscene from youtube after skipping it.
The first time was early on in the Stormblood storyline. I was queueing for something on duty finder and playing the MSQ on a different class. I forget which exact quest it was but I had entered the East Aldenard Trading Company headquarters in Kugane and was in the middle of a conversation there when DF popped. To be able to change my class and accept the queue I skipped the rest of the conversation, thinking I'd be able to watch it again through the book. Nope! Apparently those non-cutscene conversations where you retain control of the camera are not available.
Yesterday I found out that not all of the actual cutscenes are available either. I had queued for leveling roulette on my Lv67 RDM and was given an 18-minute estimated queue time. I was doing other stuff while waiting and eventually forgot about the queue altogether. I happened to be in Kugane again and saw the map marker for the final conversation of the Hildibrand quest Good Swords, Good Dogs so I changed to my Lv70 WHM to be able to do it. Lo and behold, DF popped in the middle of the cutscene and informed me of the incorrect class. This is an actual cutscene without camera control so surely I can watch it later, right? Nope! For this quest there are only two cutscenes available, one of them being the encounter in the Ruby Sea and the other being the "episode end" sequence. Watching the quest from Youtube it looks like a lot of other cutscenes were missing from the book as well.
So, why are some cutscenes missing from the book? Not knowing beforehand which cutscenes are available on the book and which are not greatly diminishes its value. If it's not possible to add everything to it, could we at least have the ability to manually cancel a cutscene and restart it from the beginning later? A DF pop can already cancel cutscenes if you're on the correct class to accept it. Closing the game cancels cutscenes, but that also makes you lose the DF pop so it's not usable here.
