 that does not make sense at all.. Everyone who watched naeuto series knows that sasuke isnt a type who is low with chakra plus knows other chakra natures too..just his perfecr ausano needs a lot of chakra yet he used it easily in naruto last aka. Borutk era to cover kurama chakra mod with his susano armor.....

Besides no one can say rinnegan is bad just because another dojutsu came, the rinnegan is still the power of sage of six paths and still has its abilities PLUS kokugan can only shrink things and sasuke can teleport with the rinnegan and much more
