Yeah last I checked you need both to get susanoo, sHashirama has healing techniques on par to that of Tsunade's Byokogu. In top of that, he has the counter for Amatersu.
Just because he hasn't shown it, doesn't mean he doesn't have it. The absence of evidence isn't the evidence of absence.
Kishi still hasn't disproved the Databook statement so therefore it stays true as it is.
If the usefulness of an attack would always be determined by how much effect it would have on Hashirama, almost every attack in the NV should be considered pointless. So frankly, I don't see your point.
If you look at my first post, you'll notice that I never said that he didn't possess it. I just said that while he may or may not have it, I find it odd that we've yet to see him use it even once, despite there being a handful of instances where the attack would have been quite useful.T you can't deny the fact that it's odd that we haven't seen him use it even once, despite the power of the attacko idk what some of the peeps are trying to preach
