What can AOE even do when you don't even know where to hit? Use those last couple of brain cells you have competently. What does Law's scan do? He only ever scanned visible objects hiding inside another visible object. We have no clue how that helps against literally invisible stuff. That's a completely groundless argument.
Help you hit your opponent? lol
It’s invisibility not immunity
Here’s an example
Fighting Aokiji would make the invisible fruit useless since Shiryu can’t fly. As long as his feet are touching the ground it doesn’t matter if he’s invisible or visible
Law’s puncture Wille has insane AOE
Unless Shiryu is one of the fastest characters in the series he’s not dodging it
