I think Oda can still draw a good back and forth fight but that isn’t really his goal here
Zoro is clearly a level above Sommers even without fully mastered ACoC and that’s what he’s trying to demonstrate
It’s just that it feels underwhelming because of how he opened the fight
Here the thing
Sommers being such a bum even before Zoro mastered COC doesn't really make Zoro look good since Sommers genuinely looking weaker than YC1s like King and Lucci, he just happens to have regen.
Showing Sommers being competitive then having him get washed once Zoro masters COC would have better to show how big of a PU it is.
Zoro fans will claim Omen Sommer is top tier of course but good luck convincing anyone else he is above opponents from arcs ago
