Watching the back and forth of this technique being claimed, unclaimed, reclaimed, etc. has been pretty fun to watch for the past few days, but it kinda irks me that this power/ability can make someone immortal to an extent without any conscious effort or expendeture of chakra. Even Tsunade and Sakura's Strength of a Hundred Seal needs some concentration of chakra stored in their forehead in order to use it's passive healing abilities, and both are masters at Medical Ninjutsu and chakra control. This makes me wonder if this seems fair to the people who've worked for it and claimed it.

Another thing. We've only seen this ability used under the influence of Sage Mode. So while it does grant instant healing without conscious effort, it probably does not have that much of an effect when NOT in Sage Mode. It's a Medical Ninjutsu technique, but it's greatest effect is only under the influence of Sage Mode, in short.

We also have to remember that this is one of Hashirama's most coveted abilities, and he was of kage power, skill and rank. But for all we know this could be due to his special Senju-ness, which anybody with Mokuton resets seems to be able to claim (sometimes even those who just claim to be of Senju descent). Even Obito has been shown to posses an extent of this power on the right side of his body, which was produced from a White Zetsu body, which are based on a living Hashirama clone, when healing an injury from a Rasengan. Though the healing process seems notably slow or delayed, since the injury isn't explicitly shown to completely heal until five chapters later. (I know that "chapters" can't really be considered a unit of time, but we do know that it is not instant.)

Someone like me could probably claim to have this with no problem at all since I easily fit the criteria, but I would rather not since I've already got some other trumps that I can rely on, and because of the questionability of this ability.
