Took the antidote from appo and helped chopper to heal everyone.
Learn to cut fire

Block the strongest attack in one piece and save everyone as kid said and kid is probably one of the toughests dudes in one piece lol.
With broken bones he was cutting promitheus with such a speed that the fire couldn't reassemble it self.
Used ashura and gave a permanent scar to the world strongest creature, saving Luffy and make law have a shocked face in the process.
Unlock adv CoC in the same arc with Luffy.

As far as character writing.
He had a couple, with the villagers and smile df, with yasui, wings moment and the bf call from sanji as well but the best moment was zoro holding enma and actually talked to the sword: oden was holding you like you were a feather line.
The realisation, no that's not enough, i would give it all and if i die, shall be it, this was a good writing for me and for the character that i like...
I don't understand what people want from zoro. To cry and ask for help? Lol
Negatives for some but not me:
No, he didn't round up the samurai, he was told by the samurai who knew the other samurai to stay low and this what he did.
No, he didn't kill kaido because he couldn't and that is all..
Sanji would beat lucci and the rest to save robin.
Luffy would beat aokiji.
Kid would beat Kaido
Etc etc.. They are warriors, having a big mouth and confidence is a must and oda has done a great job at that.. Given that he probably never have a single fistfight lol.
