Two reasons
1. Oda written style: hype moments before falling to deep hole
-ace, whitebear, kaido, law have very impressive moments (with aokiji, akainu, onshot Luffy, law attacks blackbear) before they have gone forever......
2. I feel kid vs shank, law vs teach are semi-final round, the final round is teach and shanks
This is the competition to find who is Luffy's last component
