Lol that's why I added ''you can give Nami the power to weaken Doffy's threads''...
Let me try something else, what if Cracker takes a Red Hawk to the stomach (like Doffy did) what would happen you think ? (Knowing that this will happen when fighting against Law)
Weakening Doffys threads is not equal to turning an army of soldiers that require G3+ force to destroy into edible biscuits.
There are two outcomes, one is Cracker takes more damage, he did say he doesn't like pain or something similar. The other is Cracker defends against it easily because he has stronger haki and is not affected.
Thing is Law never tag teamed against Doffy like people can theorize in this made up match.
I can just say what happens if Law teleported King Kong gun right to Doffys face etc.
Point is, making such matchups and then thinking one is better than the other is being disingenuous.
Nami is a way weaker character than Law but in that specific situation she was hard countering Crackers entire ability to fight and so swapping the supports is not the fair thing to do.
What was Laws contribution in that fight? GK? Is taking a GK and then repairing the damage partially better or worse than having your main arsenal neutralised? Keep in mind that even after GK Doffy was not pushed to the point to use awakening until Luffy brought out G4.
