It's easy to say the God's Knights are weak in terms of the verse, until you realize how many people actually have Conqueror's Haki
It's like 30 dudes
Out of the entire Beast Pirates and Big Mom Pirates, only their Captains (unless Kaido somehow convinces Yamato to join in to fight), the only two people that can actually kill the God's Knights are Kaido and Linlin.
I also think this is a big reason the God's Knights stopped fucking with the Roger Pirates and just don't fuck with the Red Hair Pirates.
Shanks' Crew is leaking CoC like
@Worstgenhq
Gyaban, Loki, Luffy, Zoro, Sanji, these people are the EXCEPTION.
I'd say we can guess there are at least 100 million people in this world, and like 30 of them can do this.
There's a reason the God's Knights are arrogant, it's easy to reach complacency when things are like this.
The God's Knights with Adv CoC, like Shamrock/Harald?
Those dudes are just absolute monsters. It took Loki + Nidhoggr + Ragnir to beat Harald. Even, Gaban couldn't put him down with Shanks' help.
The God's Knights are invincible unless you have DF Hax/CoC Haki.
The God's Knights with Adv CoC are gonna be like the Gorosei, it's going to be a monumental task to get through them.
It's why I'm really torn about Doflamingo becoming a God's Knight: I want him to do his own thing, but Omen Doffy with Adv CoC and String Awakening would be absolutely fucking nutty.
The more I imagine an Omen over Doflamingo the more I want to see Oda draw it.
