I'm glad Oda has had the confidence these past few years to take proper breaks. But it's obvious he can't put out 3 chapters a month anymore. Not only is the manga reaching the climax, but he has OPLA S2 and the next film entering production soon. And as much praise as people have been giving the spreads recently, Egghead in general has had easily the most rushed and squiggly art in the series (helped thankfully by less cluttered layouts).
If he went down to bi-weekly, it'd do the series and him a lot of good.
