Doesn't matter. It wasn't Cavendish' best attack either. They clashed equally in a physical strength context and it's all what i wanted to emphasize
Still doesn't change the fact that in an entire stadium(that was watching Luffy perfectly fine) from all angles(left, right, behind, above), only few could perceive his movements and was circling around the entire time. No matter how you look at it, it's an incredible speed feat
Depends on the type of the comment. I don't remember them complimenting his fighting capabilities. It's hype dude
Would have at best being injured from carelessness, nothing more
And when he was clashing with Chinjao alongside Luffy. And when they used combo attacks against Doflamingo fodders, etc
A singular bullet thread attack gave Law trouble on the bridge and there were multiple of them there. Distance barely matters considering Cavendish had to close distance to defend other ones himself(including Robin who could barely react) and there were multiple of them, so it required great swordsmanship skills to deflect all of them
1. The reason why you think Cavendish clashing with Chinjao was impressive is because of Chinjao's performance during his battle with Luffy, where he did use Hasshoken and Koka. So him not using either of those when he clashed with Cavendish does matter. Despite that, Chinjao still had the upper hand and you have no proof that Blue Biken isn't Cavendish's strongest attack.
2. Brook was so fast that several fishman couldn't even see Brook's movements, but I don't see you hyping up Brook's speed.
3. Point is that if someone compliments you, it doesn't mean you are at their level. It also matters who Bastille was comparing Cavendish's swordsmanship to.
4. He never did a combo move with Luffy at the coliseum. Elizabello and Chinjao did a combo move, but Elizabello is definitely a lot weaker than Chinjao. Pre TS Luffy and Biggy did a combo move at Impel Down as well, but Pre TS Luffy is leagues above him.
5. Punk Rock Fest wasn't the only time he almost got injured. When he surprise attacked Gladius, Gladius reacted fast enough and was about to use Blackium on him, but Barto's Barrier Bulls stopped both of them from attacking each other.
6. You're ignoring the reason why Law got hit. Doflamingo had already used an attack on Law and used Bullet String on him while he was recovering. Even if Cavendish had to cover some distance, he still was able to plan out what he would do when he got there since the attack was fired far away.
