I also prefer the minato fanboys now, they seem to be more mature and are not trolls. I'm a minato fan as well but not a fanboy. I admit that if he was alive, he would be very tired after what he just did, and many of his fans are overlooking that, remember that he now has infinite chakra and was revived with a zetsu clone which was made of hashirama's DNA, that alone is enough to make him about 100 times stronger than what he was when he was alive.
It wouldn't have killed him but he would be very exhausted after doing that.
