One doubt though, why has Genjutsu not been used in a long time now ? All are focusing only on Ninjutsu, Gai did on Taijutsu. but, no one tried Genjutsu. It has been many times shown in manga before, that Genjutsu can work even against Sharingan Users (Sasuke against Danzo), or Senjutsu users (Itachi vs Kabuto). It may not be the winning trump card, but can atleast be a tactical diversion, instead of Naruto wasting chakra...
