I said that in everypost. What wasn't clear to you. Why would luffy beat the entire wg the biggest faction in the story then fight bb for pk? That's the backwards of progress. After he would beat bb then what the end of the story? Luffy has to do something as pk that even Roger couldn't do. I doubt beating bb was the thing Roger was to early for. Still waiting for why it makes sense for bb to be the final villain of the series.
Luffy has to become Pirate King first. Only then he will face World Governament. That is more than clear. In in this process Teach can become King of The World and be final villain.
