It seems like noone evens remember yamato. There hasnt even been a resue squad sent for him. Its like he was fodder(well he is an anbu). Kakashi hasnt even said wait someones missing. Nothing, zip, nada. the Hokage should have suggested something i mean hes a clone of the first that is the fuel behind the enemies massive army.

They know that it's probably already to late for him. in my opinion this war arc is going way to fast. 40,000 ninja dead on the ASF side and 50,000+ dead on Tobi's side. This war is flying by to fast. It should take at least 150-200+ Chapters and the war started on 515 and is already coming to it's end and it hasn't been 100 chapters. short war!
