This got me thinking, should Oda even give Sanji adCoC? Wouldn't this skew things too far in Sanji's favour over Zoro? The entire point of the germa stuff was to make up for the lack of haki. If Oda gives him all that and then CoC ontop of that it sounds overkill atm.
Maybe he'll wait a few arcs for Zoro to get stronger before giving Sanji adCoC.
