Coby and Grus's current feats make X Drake's Wano Run even worse. Like Legitimately Grus has one of the best DF craftsmanship, even superior to Perospero and Cracker + he one shots Headliner level guys like Gotti with ease, while Coby has Advanced CoC on top of Rokushiki and Powerful CoO and Destruction capability.
X Drake on the other hand is just "Strong Enough to be F6"
I'm more certain than ever Luffy and Shanks's reunion will be a confrontation. It'll be an ironic callback to chapter 1 with Luffy standing up to Shanks for Kid and Bartolomeo when he targets the latter.
