The issue is, Kishimoto specifically draw moments of Minato talking about some special ninjutsu or something like that - we saw nothing since Kishi abandoned this idea. There are lots of important side characters who felt very short in the war, prime example is Neji who even died. Kishi didn't know how Madara should be defeated since he was op af. Was what his solution? Replacing him with a more op antagonist, great lol.
I dunno but war arc was still somewhat enjoyable and we could at least count them as "ninja gods" but Boruto? Let's just pretend it doesn't exist lmao.
I agree, the war had good moments but most stuff was too rushed and imo, the war had to be splitted in several arcs, instead it was one big battlefield with too many characters. Look how Gintama performed its war, neither Naruto nor One Piece come close to that.
