The flashback kinda established Roger is not out of reach among top tiers, and nearly established WB might just be stronger than him.
PK like we all thought, has a lot to do with having the right pieces.
-He ducked BM
-Got down on his knees for WB to make him the PK
-WB refrained from using his DF and still matched him so even their equality comes into question.
As a character, he's ok. But my initial idea of Roger was that he was actually making people bow down to him instead of running around the seas ducking confrontation, teaming up with the Navy, begging his rivals for an advantage.
