As we know, the Five Kage were awful in their fight against Madara and barely even used any of their techniques. Well, consider that again, but without their handicaps.
A has both hands, Mei isn't tired from fighting Zetsu, Gaara isn't tired from fighting his dad and the Second Mizukage, and Onoki isn't tired from fighting Mu and taking care of a meteor
I hate Kishi for making them lose so easily, anyway same Madara they fought.
Same intel, restrictions, location, and distance.
