X Drake uses his hybrid form to take down in one hit the headliner like Luffy decided to go Gear 4th to take down the other headliner. If Luffy didn't need Gear 4th why he should have used that in first place? It's a war and he needs to save his energy, I don't think he decided to waste his energy just for the sake of the show. Just look at how he decides to go Gear 4th vs Ulti only when he needed. Yamato was playing with Ulti since he didn't use any special technique or transformation and he was just blocking her hits and talking to Luffy while doing it
Just take the L and learn how to reason.
Before telling people to know how to reason,learn to look at things objectively
1) Luffy was too fast for Ulti in 1vs 1 and had the upper hand the entire time
2) Yamato and Luffy also clashed evenly
3) Yamato clashed evenly with Ulti too the second time
4)Luffy koed the number using G4 along Drake going hybrid to do the same.
Now I'm asking you,Luffy didn't need to use G4 when they were having their 1vs 1 but needed it for the number; does it mean Number>Ulti?
And since Yamato clashed evenly with Ulti the second time, Number>Ulti~Yamato???
You see how your logic works?
