People comparing him to commanders, when Shanks himself told them to back off.
Only Beckmann of the commanders still stand a chance. And even if Beckmann could have won - or lost - he would not have been one shotting Kidd or taking any arms this time around. He would have been injured himself either way. That's why Shanks stepped in. That's why Roger stepped in against Oden. Rayleigh could have won by himself but at what cost when Roger could simply one shot?
Having said that Kidds bounty is definitely inflated due to the defeats of the yonko + the fact he is a captain. Say Killer got 889M making his and Zoros 1.111 = 2B. They would without a doubt take out 3B Kidd, many even believe Zoro by himself could take Kidd.
It's not a Kidd fault, it's Odas inflation. Jinbei (250), Kuma (296), Doffy (320), Moriah (340), Law (400). These were all awarded Shichibukai status. Even unfrozen Jinbei was only 438.
All of a sudden you have Page One (290), Pekoms (330), Pedro (382), Ulti (400), Tamago (429), Sasaki (472), Black Maria (480)... How can Tamago almost be equal to unfrozen ex-Shichibukai, ex-Impel Down, ex-Sun Pirates Captain, ex-WB allied captain, current Big Mom allied captain? How can Sasaki and Black Maria be above? It's ridiculous.
Oda just keeps uping the ante to make the next antagonist seem relevant and all of a sudden 1B and even 3B means nothing as everybody is in the billions.
