Very intentional choice by Oda here, too.
We had T-Bone die pretty early in the arc (1082) due to Cross Guild hunting Marines.
Now, we see how the World Government actively reduces its own Marine forces, as Doberman and T-Bone were both Vice Admirals.
Oda's setting up the Marines rebelling against the WG really well, IMO. Underrated part of this arc. Why the FUCK would you trust the Gorosei after this shit?
