Law is like 90% DF user and 10% swordsman.
So sure he’s about as much of a swordsman as King is, who Zoro admits isn’t necessarily one.
That spread wasn’t drawn by Oda you know that? It’s from a OP magazine where fanart is featured, you don’t seriously think Oda actually handpicked this spread to tell readers that Law is a swordsman in the same way that Zoro or Shanks is?
