Yeah thats true, Act 2 was extremely stagnant, Udon felt like hell itself. Big Mom took AGES to get there, like it was her chasing the SHs at WCI all over again.
It makes me sad how much better, more concise Wano could have been. 2 years of Dressrosa and so much bloatedness and mess from that and you think Oda wouldnt learned, but NOPE, he doubled down and did an arc twice the length!
