Zoro one-shotting Lucci was already expected.
I was expecting a Lion Song but I guess Zoro needed Santoryu, props to awakened Lucci, a legit YC1, even King would get folded by that if Zoro gets him clean.
But this just confirms Zoro was playing around, or more like Oda is stalling Zoro, again, and had to get him out of Vega Punk's sight or Kizaru would've been cut.
Oda simply doesn't have enough time to creatively write other characters.
Look at Jimbo, another prominent fighter doing nothing the entire time but running errands. Doesn't the smartest scientist have some robots to do what Jimbo has done?
