Oda :
Writing battles between 3B class fighters
Hyping Yonko lately over other 3B fighters
Luffy trained specifically to surpass Kuma, Sentomaru and Kizaru
You guys "zoro should fight and beat Kizaru, because it make senses, you see.."
Let it go!
Zoro isn't beating an admiral before Sanji does
Even when they fight marines/WG, Sanji will first beat his opponent before Zoro does per usual
It's Luffy vs Kizaru
Or Kizaru vs Wings
Zoro can't beat a Top tier 1v1 or push then last mid diff then go on fighting Shiryu later on
