No, it's just that almost every character in the NW has attack power far >>>>> a damn tree bark lmfao. Kelly Funk got struck by gladiators weilding axes and the axes shattered against his body. And Doflamingo's string clone one shot Kelly Funk with utter ease. Thus, characters far more durable than Tree BArk still need to dodge, as breaking through tree bark is an utterly pathetic feat by OP standards.
So I'm sorry Ikoku has yet to show the attack power of Doflamingo's casual string clone. Lol
