Luffy often leaves arcs weaker than the arc villain. This is very evident in wano, with current Luffy still being weaker than Kaido.
The same will likely happen in Elbaf with Teach.
Oda has already set up Law and Shanks as rivals of Teach, chances are, they’re going to put in work against Teach.
Shanks will payback Teach for his eye scar and Law will get revenge for his loss.
This will ultimately have the same effect as Zoro and Yamato’s help in wano, giving Luffy assistance so he can recover after being temporarily defeated.
