Regarding the plotholes of Gladiolus getting his scars, Ignis going blind and Prompto being kidnapped/being Verstaels son:
I see so many people wondering what all that is about. But isn't it obvious that the announced DLC missions will cover these events?
It's especially clear with Ignis and Prompto. The info we got about their missions fits perfectly with what little we learned in the story about their disappearances.
Ignis went blind while helping to evacuate Altissia. His DLC mission will be strategic in nature, that they already told us.
Prompto fell off the train shortly before reaching the snowy regions. We know from the DLC concept art that he will be in a snowy region in his mission.
Just for Gladio we hardly know anything other than that he met with someone to take care of something. It will probably also explain a plothole we can't connect it to yet. I have a hunch that in it we will also get closure with Cor who just vanished from the story.
Im pretty sure the actual game was meant to have all solo missions in the game, Gladio first, than Ignis, then Prompto and then finally Noctis' solo mission in chapter 13. That seems to make perfect sense to me at least.
The second half of the game felt very short, rushed and unfinished. The absence of these three missions is probably the reason.
Didn't they also claim the pure story content was about 40-50 hours long and then we found out is is a good 10-20 hours shorter? I think it's strange that they were so off the mark. But back than, including the 3 missions, the story content was probably 40-50 hours long.
