The problem with Jon is that he is flawed in all the worse places for an MC and a leader. Believing himself inferior (or at least not worthy of his titles or names, true names), naive in a way, not cunning, easily trusting. Let's ignore this entire 3 chapters, they were very long to read, very tedious, it was basically a repetition of showing how he failed, lost his mind (after dying). It implied the past, before the Long Night, they had more people, more powers.... how did they lose? How will Jon make a difference as he is? Weak (and not even considering mentally), he is human level at best, if the past armies didn't win what would he do? Frankly, with out you described the past and the enemies, even if Jon was (Movie) Superman I would not believe he could win. He could survive but not definitely win and save everyone else. In novels, what is written is not as important as what the readers can believe, so all I am thinking..... how will this proceed, a normal human in that past, with his personality? No chance, will require constant plot armor to survive (something like HP, Potter "Luck"). Writing quality... excellent, grammar and just the general description of everything.
