Susanoo is wall of Chakra , A is Covered with Lightning
Is touching Chakra and Touching Lightning the Same to you ?
and You , Chatte and Slug Princess seem To forget that A's Punches, Elbow and Horizental Chop attacks have almost the Same power as tsunade's Punches
so A is Basically Tsunade's Power Blitzing Speed
raikage touched sasuke when he wanted to do liger bomb,nothing happened,and tsunade is punching him,not touching him just like the raikage and sasuke's enton ribcage,and any damage done heals intsantly and the punch will still kill the raikage regardless.
You seem to be forgetting that his attacks when bolstered up by onoki barely hurt madara in his susanoo,tsunade alone blew it and madara apart,the shock wave of her heavenly kick of pain knoecked down 2 houses,thr raikage's liger bomb didnt come close to that,the raikage isnt even close to tsunade's strength,his v2 chop couldnt break madara's ribcage susanoo,tsunade's hit wiped out madara's complete susanoo madara at the same time,tsunade used a finger to cause a fissure in the ground.
The raikage is NOWHERE near tsunade's strength,not to mention chakra infused punches,she took a magatama from madara and didbt flinch,his punches wont do anything.
