This is why you need to read before spouting nonsense. They were constantly under attack and were effectively countering everything thrown at them:
It's only when King came they found themselves helpless:
Big Mom is the first to notice him from afar. They just weren't quick enough to react. No one gives a flying rat's ass about kicking a ship around. It's the people who sail onboard that matter. BM pirates openly admitted they can't reach Wano as long as King is guarding the skies implying they can't do anything about him even if they're prepared. King essentially ended BM's career to the point that they started nominating the next captain. Your favorite "Katakuri's is foreshadowed as the next captain of BMP" moment only happened thanks to King.
This is the worst humiliation any pirate crew can ever suffer. You're lying to yourself if you think this is not something big.
