Im no naruto expert so pliz someone hold my hand as cross this street, and I wld rather a lady do this(just kidding bros but just help me out)
I. The 8gates tech is leting all the chakra being limited by the "gates" run wild/loose and free, and all the physical changes are effects of too much chakra circulating in one's body and this is what harms the body while using this tech. So in summary one cld just say 8gates tech is abandoning all chakra control and just overloading the muscles and thats what makes it perfecy for taijustu(all chakra to muscles).
II. Strenght of a100 seal, is a tech that requieres great chakra control in that the user focuses and stores their chakra in one spot on their body over long periods of tym. When released the chakra boosts their medical and phyysical aspects(so far so good),
but when one opens 8gates chakra run wild.and free withoughy limitations while the seal is massive chakra limitation in one spot so activating 8gates first cld lead to the seal being undone and the stored chakra being flushed away in the rage of thr storm of 8gates chakra.
Pre releasing yin seal then releasing 8gates wld IMO have the same effect think of it as like a stream being followed by the surge of a burst dam wall, I dont think all the water will follow the meandering of the stream, it just flows in a large wave no meandering.
Same tym release, then wldn't the stronger of the two chakra signatures b the deciding effect.
If it does work by some.miracle then the tear caused by 8gate and the so not good for u healing of the other tech just mean u are just waiting a few seconds before this antagonistic chakra relationship eats up all yo chakra coz well 8gate will run out sometime coz even with limitations removed u still have a time limit relevent to how much chakra is being used per miniscual time interval and Tsunade seal also has the same effect as its like a water tank being used, it runs dry soon enough and in this case even while just standing 8gates are tearing up yo body so Tsunade seal is healing u(using yo chakra and also drawing yo life limit closer)
How do u guyz say it wld work and even if it does the effects of both just make it un worth it and also can 8 gates b used for medical/ninjistu practise???? Im not saying it cant b used just someone help me maybe I understood stuff wrong.
