I think the MC need to start building his crew Grand Fleet before going to New World, right now the pace is too fast, even when Ace is still captured, but many interesting encounters are lost because of the fast growth of the crew. Well, I understand some are not that needed, but I think those encounters are still needed to build their influence and army. Maybe after the summit war, you can make all crew train their character to 100% and also their haki, before going to the new world. It's just my idea, except you will make this fanfic become multiverse fic, like after finishing one piece arc, they are going to another universe, so they need to finish this quest fast.
