Sage mode should have been Senju/Uzumaki bloodline limit.

Now to start with why I think this. This is because although the uchiha are cool kishi has put so much effort into developing their powers that most people cannot conceive of the senju being more powerful. To be perfectly honest i don't blame people who think the uchiha are better because of sharingan. Hashirama is the only senju that has a special ability amongst the senju. If the senju/uzumaki have a bloodline limit like that has the same properties as sage mode not only will it fit the "the body of the sage" inheritance thing that they have, but it will also allow them to have an answer to the sharingan. let us now see what each inherited from the rikudou

From what we can see here both sons inherited three things from the sage. But let us pay closer attention to what the younger son has. Most of what the younger son had was taken from him and given to other ninja clans as well as his descendants leaving them not so special. First is the "body". The "body of the sage" means that the person has healing abilities and a resilient body as well as makiing good jinchuriki . Now many of the younger sons descendants posses this.

However the main problem is that other ninjas who may be unconfirmed yonger son descendants have these abilities aswell.

Kimmimaro has shown great healing abilities as well as a resilient body the only thing he has not covered is being a jinchuriki which is rare for people to be anyway.

Now the next category is life force and physical energy. These go together as shown in obitos creation of all things explanation

Now "the sages life force" grants long life and high chakra reserves. Long life has so far only been emphasized on uzumaki however high chakra reserves have been shown on non younger son descendants like kisame and the raikages

As one can see most of the traits that descendants of the younger son have are shared with other special shinobi. Although these ninja could also be descendants of the younger son it has not been proven by the manga so we can't work with just speculation.

The elder son descendants ( don't bring hyuga cause it's not cannon) the uchiha share certain attributes with other shinobi such as powerful chakra and high spiritual energy but not the eyes. Because the sharingan is unique to them and is what sets them apart. The senju/uzumaki also need something like that to show that they are descendants of the rikudou aswell. This is why I came up with the idea of sage mode. Although kishi has made it canon that the uchiha were inferior to the senju as a reader apart from hashirama, tsunade, naruto, nagato and resently now tobirama. There is nothing definitive that puts the senju above the uchiha. We just have to accept what kishi gives us.

Thoughts?

The Senju/Uzumaki have heavy chakra pools, which facilitates the transition between base mode and Sage mode, as Pa explained to Naruto. Were someone with lower chakra pools to try and absorb nature chakra, they would be turned to stone quite easily. It could be possible for someone with very powerful chakra control to learn Sage Mode anyway, but someone with large chakra pools (Senju/Uzumaki) would be able to learn Sage Mode with several mistakes inbetween, while those that don't would have been stoned immediately.

Edit: There's also the idea that, because they have heavy chakra pools, Senju/Uzumaki members can also absorb more nature chakra which makes their Sage Mode last longer and have more devastating effects. Someone with a lower chakra pool can only absorb a little bit of nature chakra to complete the 33/33/33% ratio of chakra.

I see your point. But the point of my thread is certain lucky ninja can have traits of the younger son but no ninja can have traits of the elder son unless they are uchiha.
