Does anyone realize that the headquarter's destruction doesn't confirm a loss? The revolutionaries could've won, but has their headquarters destroyed in the fight.
–- Update From New Post Merge ---
This arc was only twenty chapters and it was better than Dressrosa. And arguably more impactful for the overarching story.
If there even was a fight at all. If the Government had won I'd figure the paper would say Marine destroy Revolutionaries or some such. And if they had lost I doubt anything would have made the paper given how they control the news. However the paper only says Baltigo destroyed so it's possible that the government only arrived there after the revolutionaries had left. Afterall if Dragon attacks Marie Joa during the Reverie he is likely to use all his forces.
