Well, you are right about the little things that happened at the end. I forgot about those. Well, at least a small consolation.

Yet, like you said, the foxy pirates seem to be running all the event, but why is that? If we were honest, Luffy, Zoro, Sanji and Robin could beat the hell out of the Foxy pirates in an honest fight. The foxies don't seem to have any other extraordinary fighting power but their captain's devil fruit power. And that would be dealt with easily enough with a little distraction. So, taking that into account, why do the Strawhats agree to let the opponent run the event?

I mean, it's retarded to allow one regular member of the opponent to be the ref! Take some NHL game, and consider what would become of it if one of the two teams facing each other would be allowed to just appoint some of their own players as the referee for the match. You can bet the other side would get most of the penalties, and their own misdeeds would somehow go unnoticed.
