You purposefully ignore foreshadowing if you think Saint Shanks and Teach won’t fight lol. It’s been the most abundantly clear thing in the manga besides Luffy becoming pirate king.
Why would Oda reduce Luffy's opponents? You didn't answer.
He is already doing it via Law and Kid, they made them fight Bb and Saint Shanks. And you want Saint Shanks fight BB too after? Lol.
