He has the sword for a reason. And Law isn't getting grabbed in the first place unless BB gets help.
BB could suck him in and deprive him of objects to switch with. He's totally capable of touching Law. Saying "he has a sword for a reason" doesn't accomplish anything. Law can't even compete with the people on his level without his devil's fruit ability, forget about a Yonko with the most destructive ability in the world.
How is it groundless though when we know for a fact that haki mitigates damage.
That means anyone from Amazon Lilly fodder to Mihawk could mitigate damage from GGnM. I doubt you guys are tying to argue Law fights BB by mitigating 0.001% of GGnM power.
But how does blocking five colored string reduce Law's haki? It is not like that was even his limit.
Well, I didn't say it reduces his Haki. I said that's the best feat he has so far.
Not every single attack from GGnm is island-wrecking though.
Doubt BB's not gonna capitalize on the opportunity and use a tiny building-level punch though. Even the weakest of GGnM attacks are well beyond any single hit move Law managed to withstand without hitting the ground.
In fact only a few are and they require some prep to release.
No preparation, he just needs to take a stance and it's not an absolute necessity considering WB attacked Akainu without taking a stance the first time he attacked him.
Law's COA strength can be superior to Luffy's even though Luffy has the better technique (barrier and penetration)... both are exclusive of each other
Groundless, Law's CoA was superior to Luffy back in Dressrosas. Luffy's Haki grew since then, and we have no reason to believe Law's Haki is superior to his now.
