Those pros are going to likely outweigh those cons for me, as they seemed to for you as well. You know what's worse than a story that's a "mess" overall but has a strong group of characters that has a great ending? A good story that isn't a mess but that has a total limp-dick finale and conclusion ala FFXII.
Now, I wish it were good all around obviously, but I feel like it's more disappointing when something is really good and then deflates by the end. It sounds like XV is the opposite of this. The final impressions are always the lasting ones, so if it goes out with a bang and has a great ending, it may improve my opinion of the story overall as opposed to it being good for a while and then having a lackluster conclusion.
Also if it actually ends up making sense and isn't super convoluted, that's always a plus. I get that the pacing may be off and that it even hits MGSV syndrome of nothing happening at all for stretches, but if the story is okay to follow instead of something like FFXIII and has a great ending, I think I'll be fine.
It's... Well, for the story I felt like there was enough context to get an understanding of what happened so long as you pay enough attention to the surrounding stuff. I don't wanna say it's relying on it, but it does stop itself from devolving into, over-explaining what the hell is going on for better or worse. Personally I enjoyed it because, man, I just do not care about the nitty gritty most of the time. This thing is happening, it needs to be fixed. Baddabing, baddaboom.
