in every yonko crew we had insane hype over the 1st yonko commanders
katakuri had a bounty over a billion, future sight and had that invincible track record.
even the gorosei thought marco was gonna become a new yonko + all the action at marineford. even before all that, shanks wanted him to join his crew.
benn beckman literally stopped kizaru with a pistol at marineford.
and then we have king, the man that gets embarassed by raid suit sanji, gets caught off guard by izo, fails to stop zoro from going to the rooftop. dont even place king on the same level as the other yc1. he has had nothing that warrants that ~ except maybe his race but i doubt that'll be a huge thing at this point.
