I'm just saying, the other Kage were as close to him as Tsunade, she was in front of his face, punched him in the chest, wouldn't your first thing to be to put her under a spell.
He obviously had genjutsu attacks, as seen with the Raikage.
Tsunade was in direct contact with him, and looked him in the eye many time.
While punching him and his sunsanoo.
What do you guys think the reason behind this was,
Genjutsu would've been the smart move, after having your shield broke, and being ripped to peices.
