@Sereques:
Interesting note, Mingo have never once said he wants to be PK.
2) Mingo has a psychological advantage over Law and a full knowledge on how Law's DF works.
While yes this is true, Dofla still had taken hits due to his DF (shambles). Regardless of knowledge on a DF you will still get hit.
It's like watching videos and reading how to defend yourself, yet when your up against someone in practice, it simply isn't going to work as you'd imagine.
Practical and theoretical experience are very different. Dofla was on the theoretical side.

@Monkey:
At first, Luffy's goal wasn't to kick Mingo's ass, they were juste supposed to give Caesar back and destroy the factory.
It was to help Rebecca who paid him a snack and because Franky couldn't let down the tontatta's people that Luffy decided to get involved in this battle.
I'm talking from a readers perspective when i say Luffy walked in to Kick Doflamingos ass.
To be fair, Luffy did mention before entering Dressrosa, directly to Dofla he would kick his ass if he pulled some shit off again. He was already pulling it.
