i will never forgive Oda for screwing up the most interesting female character in the whole story. in a perfect world where Oda isnt a bumfuck who gave up on thinking while writing one piece a decade ago and if he had matured beyond 8th grade with the perception of women as either ickly girly females or fap material (50 year old man btw).
in that perfect world Tashigi wouldve been Zoro's full marine counterpart, Koby but with a stronger connection to the strawhat crew.
she wouldve evolved throughout the story. maybe learning actual fighting techniques maybe had ACTUAL FIGHTS herself and collected a legendary sword or two. and wouldve been Zoro's rival/conflicted friend like mihawk. also elevating Zoro beyond le aura powerscaling man.

but no.
in our reality we got a forgotten character that appeared again for one arc to get fully embarrassed, realistically only will reappearing during the final big fight as a background npc with Smoker.

(also all of this goes true for Smoker himself too but thats another story.)
