Considering Luffy has been through the tourney that has only happened a couple hours ago in the manga and been ambushed by Doffy once and manipulated into awkwardly protecting Bellamy while taking an assault from doffy. He was also fighting his way through hordes of enemies before ever reaching doffy. Kicked out, then takes haki hits from Bellamy because he would refuse to fight.
Doffy has only been hit twice if that? And I might have missed some things. I'd say Luffy has taken a bit more of a beating than Doffy. Even if Law helped him on the first hit I really can't consider this a team battle. But whatever. If anything help will be so minimal in such a big way though if there is to be help. Law being out of commission is just so Luffy can have a 1v1 with doffy. The plot protection really only work with the main character, don't really think it works with side characters haha.
