Okay his detachment of the primitive world technique is pretty cool. But how many times can they use it consistently? I know Oonoki only used two? On Mu, meaning it takes a lot of chakra to use it.
And also the Black Lightning technique is the same one used by Darui. And let's all be realistic, Darui is super strong, arguably, as strong as Kakashi. And the Third Raikage, being the mentor of Darui, I would expect to his Black Lightning to be stronger than Darui's.
I agree with the rest of what you said, though.
I forgot to mention in my previous post, that when i added Onoki in the list i meant an healthy Onoki (Not necessarily young) but without his back pain. xd
Onoki was using his Jinton against another jinton user who was also his master, and maybe more powerful then him, so to stop his attack onoki had to pour more chakra then what he uses for normal Jinton, since he had to overpower Muu's attack in order to protect himself and the other's, and he was also using various Doton based ninjutsu that's why he needed chakra from Tsunade to do a powerful Jinton attack.
But muu was not able to use jinton when he was split in half because it divided his chakra as well, so it is more or less true that a high lvl tecnique like that will demand more chakra then usual, but i do not think that it is as demanding that you can only use two or three attack, and specially when you are simply trying to attack a single target, like what onoki used on sasuke at the summit.
Well, with that being said, it actually does not matter for a jinton user that how many time he can hit his target, since it requires only one precise hit, and in this case Muu is Raikage's worst opponent, because he can turn invisible and hide his chakra signature and present completely from a person who does not has a Dojutsu to see him, he can go right behind him and hit him with a powerful jinton, and one hit that's all he is gonna need.
EDIT:Jinton user's use 3 different chakra nature's, and can use their attack's to create an opening for them to take a shot at their opponent.
Darui is a strong ninja and he has more chakra then Kakashi for that matter, but that black lightning was not really up to my expectation, he could not kill many of the zetsu clone even when he used it on a beech (Kakuzu simply jumped above and was not even affected by it),if that's all it has to offer then i do not think it will kill any of the mentioned, and even current kage in one hit even if it connect's (which is hard imo),
i know that 3rd Raikage will be stronger then him in that jutsu,but not much, see Muu and Onoki for example.
I am not disregarding his power lvl in any way, he is strong, but it is all about a bad match up, like if you put Garaa against Kisame, then there is not much he can do about it, because he uses sand for attack and defense and Kisame is a high lvl Suiton user who can create an entire lake in an instant.
