@Dawn HxH was a big meme really. The author is probably just getting himself confused on how to end it properly and tie everything together which is why we're scattered all over the place. Dude's a dummy. Just by analyzing when the final arc started, you could tell he doesn't really know how to end it and tie all the loose ends. Could be a corporate issue could be a personal issue could be a skill issue. Either way this is disappointing. Attack on titan really set the bar high as he** when the story/ending was all planned from the beginning and came together perfectly.
