^^^ You're right, but you gotta remember that Katakuri said it himself, he outclasses Luffy in both speed and power. So for Luffy to win the fight, which we all expect via plot armor no jutsu, he has to find a way to gain an edge in those categories. Luffy has consistently fought opponents that outclassed him in either, sometimes both, but in the end it comes down to him activating a power up that does the job. Again, you're right in that if Katakuri survives G4 Luffy is pretty screwed, but what other options does he have? You should have known from Doflamingo that G2 and G3 alone are just not gonna get the job done anymore by themselves. And that was what I didn't like about the Doffy fight, he got to be protected so he could recharge for G4. I wanted to see Luffy learn to find a way around that limitation, like he did for G3. Here he has no choice but to find a way to keep himself in the fight, so I'm excited to find out what that's gonna be. I wouldn't be surprised if by the end of the fight, he says something to the tune of, "thanks to you, I can protect my crew even better now".
