1)namikaze minato means waves wind harbour
2)A is supposed to be the fastest shinobe of his time but he couldnt touch minato when he did have a chance.
3)the match ended with a mexican stand off with bee and minato. had minato wanted to kill them there would have been no pause with bee and be would have been lying there with a kunai in the back of his head.
4)theres technically no running away from the fastest man in the world. that thought is a paradox in itsself. 5) you still didnt tell me how the rasengan wouldnt have completely destroyed a's lightning armour. remember....cellular level
