Realistically, what could that version of Sanji had done?
Maybe with the raid suit he could take some hits for the team and served as a distraction due to invisibility - but that's really the extent. Definitely isn't doing anything much damage-wise, at that point.
Oda was better off giving him the Black Maria subplot, which served as good character development for him IMO.
But really... I thought y'all would have matured from this cringy Sanji slander. It's honestly childish
