How has Obito been able to spam his MS technique so often and not go blind, he doesn't have EMS and only one eye and his fighting style revolves heavily around this? Can anyone explain? Is this the Senju DNA? Also why is he holding back while fighting Naruto and co. he could have absorbed Naruto's rasengan or even used almighty push to stop himself from getting hit, on top of that he is not using mokuton. Obito has so much potential he either just sucks or is not trying.
