ITT people find out zoro is not the main character despite being told that every day in the last 4 years
Sanji is WCI was WAAAAY more important than zoro in wano.
of course because wci arc was about sanji and his family. the arc only happened because luffy went there to rescue sanji.
wano never was about zoro it was about momonosuke and his family. the only connection the arc had with zoro was there are many swordsman there and the possibility of zoro family being from wano but the arc was never about zoro or his issues or his family or anything related to zoro.
people had not reason to expect wano to be zoro wci arc but people decided the arc was about zoro and they decided zoro would become one piece main character and now are taking a shit on the writer for not doing it.
just because sanji got an arc does not mean zoro gets one arc too = just because zoro always gets cool moments and big feats does not mean sanji gets those too. oda does not own to one character something just because the other got it.
