Still, the first arc after the time-skip is presumed to reveal the Strawhats new powers, so a weak opponent doesn't really fit in. Therefore, I believe that there will be a major enemy in this arc. Also, I agree -beating a Yonkou would make One Piece into another Dragon Ball, but as of how things are now, they need a bigger enemy, and Big Mam fits into the story.
